Chapter 5: Q7DQ (page 1180)

Could the Young two-slit interference experiment be performed with gamma rays? If not, why not? If so, discuss differences in the experimental design compared to the experiment with visible light.

Short Answer

Expert verified

Due to the unavailability of the monochromatic source of gamma rays, it is not yet possible to perform the experiment. But theoretically, it is possible.

Step by step solution

01

Interference of light

The necessary and essential condition for the light waves to interfere is that the light waves should be coherent and monochromatic. If the light waves are not monochromatic, then instead of dark and bright fringes we will get cultured fringes.

02

Determine whether it is possible to perform a two-slit interference experiment with gamma rays or not.

Due to the unavailability of a monochromatic source of gamma-ray, it is very difficult to perform Young鈥檚 two-slit interference experiment with gamma-ray. The experiment can be performed theoretically. But the wavelength of gamma rays is very small. As a result, the fringe width of the pattern will be too small to be observed.

Hence, Young鈥檚 two-slit interference experiment can be performed with gamma rays, theoretically but is very difficult to perform practically.

The laws of optics also apply to electromagnetic waves invisible to the eye. A satellite TV dish is used to detect radio waves coming from orbiting satellites. Why is a curved reflecting surface (a 鈥渄ish鈥�) used? The dish is always concave, never convex; why? The actual radio receiver is placed on an arm and suspended in front of the dish. How far in front of the dish should it be placed?

The left end of a long glass rod 6.00 cm in diameter has a convex hemispherical surface 3.00 cm in radius. The refractive index of the glass is 1.60. Determine the position of the image if an object is placed in air on the axis of the rod at the following distances to the left of the vertex of the curved end: (a) infinitely far, (b) 12.0 cm; (c) 2.00 cm.

You are sunbathing in the late afternoon when the sun is relatively low in the western sky. You are lying flat on your back, looking straight up through Polaroid sunglasses. To minimize the amount of sky light reaching your eyes, how should you lie: with your feet pointing north, east, south, west, or in some other direction? Explain your reasoning

When a sheet of plastic food wrap is placed between two crossed polarizers, no light is transmitted. When the sheet is stretched in one direction, some light passes through the crossed polarizers. What is happening?

In using the superposition principle to calculate intensities in interference patterns, could you add the intensities of the waves instead of their amplitudes? Explain.
