D

Radio waves are readily diffracted around buildings whereas light waves are negligibly diffracted around buildings.This is because radio waves:

B

Diffraction plays an important role in which of the following phenomena?
Free
Multiple Choice

C

The rainbow seen after a rain shower is caused by:
Multiple Choice
When a highly coherent beam of light is directed against a very fine wire, the shadow formed behind it is not just that of a single wire but rather looks like the shadow of several parallel wires.The explanation of this involves:
Multiple Choice
When the atmosphere is not quite clear, one may sometimes see colored circles concentric with the Sun or the Moon.These are generally not more than a few diameters of the Sun or Moon and invariably the innermost ring is blue.The explanation for these phenomena involves:
Multiple Choice
The shimmering or wavy lines that can often be seen near the ground on a hot day are due to:
Multiple Choice
In order to obtain a single-slit diffraction pattern with a central maximum and several secondary maxima, the slit width could be:
Multiple Choice
A point source of monochromatic light is placed in front of a soccer ball and a screen is placed behind the ball.The light intensity pattern on the screen is best described as:
Multiple Choice
At the first minimum adjacent to the central maximum of a single-slit diffraction pattern the phase difference between the Huygens wavelet from the top of the slit and the wavelet from the midpoint of the slit is:
Multiple Choice
At the second minimum adjacent to the central maximum of a single-slit diffraction pattern the Huygens wavelet from the top of the slit is 180 out of phase with the wavelet from:
Multiple Choice
A plane wave with a wavelength of 500 nm is incident normally on a single slit with a width of 5.0 10-6 m.Consider waves that reach a point on a far-away screen such that rays from the slit make an angle of 1.0 with the normal.The difference in phase for waves from the top and bottom of the slit is:
Multiple Choice
In the equation sin= /a for single-slit diffraction, is:
Multiple Choice
No fringes are seen in a single-slit diffraction pattern if:
Multiple Choice
The diagram shows a single slit with the direction to a point P on a distant screen (not shown).At P, the pattern has its second minimum (from its central maximum).If X and Y are the edges of the slit, what is the path length difference (PX)- (PY)?
Multiple Choice
The diagram shows a single slit with the direction to a point P on a distant screen (not shown).At P, the pattern has its maximum nearest the central maximum.If X and Y are the edges of the slit, what is the path length difference (PX)- (PY)?
