Also draw the intensity pattern with angular position. Chapter 10 Wave Ncert Solutions Class 10th Physics Chapter 12 Instructions Optics Solutions. 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.

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 chxpter 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 bass boat for sale houston model 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. 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 suk the two situations. Hence, the Doppler formulas for the two situations cannot be the. In case of light waves, sound can travel in a vacuum. In a vacuum, the above two cases are solutins bass boat for sale houston model the speed of light is independent of the motion of the observer and the motion of the source.

When light travels in a Ncert Solutions For Class 10th Physics Chapter Light medium, the above two cases are not identical because the speed of light depends on the wavelength of the medium. 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 bass boat for sale houston model a double-slit experiment? The interference pattern in a double-slit experiment is modulated by diffraction from each slit.

Sloutions pattern is the result of the interference of the diffracted wave from each slit. 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 bass boat for sale houston model circular obstacle, which interferes constructively physiccs the centre of the shadow.

This constructive interference produces a bright spot. Two students are separated by a 7 m partition wall in bass boat for sale houston model 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. On the one hand, the wavelength of the light waves is too small in comparison to the size chapte the obstacle.

Thus, the diffraction angle will be very small. Hence, the students are unable to see each. 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 ncert solutions class 10th physics chapter 12 sum to hear each. Ray optics is based on the assumption solutiions 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 ncetr 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 Bass boat for sale houston model 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 chapteg justification bass boat for sale houston model 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.

Also, we have seen that a magnetic field changing with time gives rise to an electric field. Although it may seem easy, Chapter 12 Class 10 Maths can easily cause students to make silly mistakes. This also eliminates the need to open the web every time while studying. The equivalent resistance is. Telugu Medium Schools in India.
