NCERT Solutions for Class 10 Science Chapter 10- Light Reflection and Refraction
Similarly, a plane mirror will always give a virtual and erect image of same size as that of the object placed in front of it. Therefore, the given mirror could be either plane or convex. Video Solution for light reflection and refraction Page: , Q. Also, magnification is more for convex lenses having shorter focal length. Therefore, for reading small letters, a convex lens of focal length 5 cm should be used. What should be the range of distance of the object from the mirror? What is the nature of the image? Is the image larger or smaller than the object? Draw a ray diagram to show the image formation in this case. Hence, to obtain an erect image of an object from a concave mirror of focal length 15 cm, the object must be placed anywhere between the pole and the focus. The image formed will be virtual, erect, and magnified in nature, as shown in the given figure.

Answer: a Concave b Convex c Concave Explanation a Concave mirror is used in the headlights of a car. This is because concave mirrors can produce powerful parallel beam of light when the light source is placed at their principal focus. Convex mirrors give a virtual, erect, and diminished image of the objects placed in front of it. Because of this, they have a wide field of view. That is why they are used to construct solar furnaces. Concave mirrors converge the light incident on them at a single point known as principal focus.

Hence, they can be used to produce a large amount of heat at that point. Will this lens produce a complete image of the object? Verify your answer experimentally. Explain your observations. Answer: The convex lens will form complete image of an object, even if its one half is covered with black paper. It can be understood by the following two cases. Case I When the upper half of the lens is covered In this case, a ray of light coming from the object will be refracted by the lower half of the lens. These rays meet at the other side of the lens to form the image of the given object, as shown in the following figure. Case II When the lower half of the lens is covered In this case, a ray of light coming from the object is refracted by the upper half of the lens. Draw the ray diagram and find the position, size and the nature of the image formed. The negative sign shows that the image is real and formed behind the lens. The negative value of image height indicates that the image formed is inverted.

Important Questions on 12th Physics Chapter 10 Is the speed of light in glass independent of the colour of light? If not, which of the two colours red and violet travels slower in a glass prism? The speed of light in glass is not independent of the colour of light. The refractive index of a violet component of white light is greater than the refractive index of a red component.
Chapter 10 - Rotation - Questions - Page 286: 1a
Hence, the speed of violet light is less than the speed of red light in glass. Hence, violet light travels slower than red light in a glass prism. What is the Brewster angle for air to glass transition? Explain how Corpuscular theory predicts the speed of light in a medium, say, water, to be greater than the speed of light in vacuum. Is the prediction confirmed by experimental determination of the speed of light in water? If not, which alternative picture of light is consistent with experiment? Hence, the normal component of velocity increases while the component along the surface remains unchanged. The wave picture of light is consistent with the experimental results. For sound waves, the Doppler formula for frequency shift differs slightly between the two situations: i source at rest; observer moving, and ii source moving; observer at rest.
Samacheer Kalvi 12th Physics Solutions Chapter 10 Communication Systems
The exact Doppler formulas for the case of light waves in vacuum are, however, strictly identical for these situations. Explain why this should be so. Would you expect the formulas to be strictly identical for the two situations in case of light travelling in a medium? No Sound waves can propagate only through a medium. The two given situations are not scientifically identical because the motion of an observer relative to a medium is different in the two situations. Hence, the Doppler formulas for the two situations cannot be the same. In case of light waves, sound can travel in a vacuum. In a vacuum, the above two cases are identical because the speed of light is independent of the motion of the observer and the motion of the source. When light travels in a medium, the above two cases are not identical because the speed of light depends on the wavelength of the medium.
NCERT Solutions for Class 12th Physics
In a single slit diffraction experiment, the width of the slit is made double the original width. How does this affect the size and intensity of the central diffraction band? In a single slit diffraction experiment, if the width of the slit is made double the original width, then the size of the central diffraction band reduces to half and the intensity of the central diffraction band increases up to four times. In what way is diffraction from each slit related to the interference pattern in a double-slit experiment? The interference pattern in a double-slit experiment is modulated by diffraction from each slit. The pattern is the result of the interference of the diffracted wave from each slit.
NCERT Solutions for Class 6 Science Chapter 10: Motion and Measurement of distances
When a tiny circular obstacle is placed in the path of light from a distant source, a bright spot is seen at the centre of the shadow of the obstacle. Explain why? This is because light waves are diffracted from the edge of the circular obstacle, which interferes constructively at the centre of the shadow. This constructive interference produces a bright spot. Two students are separated by a 7 m partition wall in a room 10 m high. If both light and sound waves can bend around obstacles, how is it that the students are unable to see each other even though they can converse easily. Bending of waves by obstacles by a large angle is possible when the size of the obstacle is comparable to the wavelength of the waves.
NCERT Solutions for Class 11 Physics Chapter 10
On the one hand, the wavelength of the light waves is too small in comparison to the size of the obstacle. Thus, the diffraction angle will be very small. Hence, the students are unable to see each other. On the other hand, the size of the wall is comparable to the wavelength of the sound waves. Thus, the bending of the waves takes place at a large angle. Hence, the students are able to hear each other. Ray optics is based on the assumption that light travels in a straight line. Yet the ray optics assumption is so commonly used in understanding location and several other properties of images in optical instruments. What is the justification? The justification is that in ordinary optical instruments, the size of the aperture involved is much larger than the wavelength of the light used.

When a low flying aircraft passes overhead, we sometimes notice a slight shaking of the picture on our TV screen. Suggest a possible explanation. Weak radar signals sent by a low flying aircraft can interfere with the TV signals received by the antenna. As a result, the TV signals may get distorted. Hence, when a low flying aircraft passes overhead, we sometimes notice a slight shaking of the picture on our TV screen.

As you have learnt in the text, the principle of linear superposition of wave displacement is basic to understanding intensity distributions in diffraction and interference patterns. What is the justification of this principle? The principle of linear superposition of wave displacement is essential to our understanding of intensity distributions and interference patterns. This is because superposition follows from the linear character of a differential equation that governs wave motion. If y1 and y2 are the solutions of the second order wave equation, then any linear combination of y1 and y2 will also be the solution of the wave equation. Related Links.
