A narrow stream of electrons of energy 100eV is fired at two parallel slits very close to each other. The distance between the slits is 10A. The electron waves after passing through the slits interfere on a screen, 3m away from slits. The fringe width is

View answer and explanation

Correct option: A

0.36m

Option A (0.36m) is correct because it is calculated using the de Broglie wavelength and the fringe width formula for electron interference.

reach a point in opposite phase. The resultant amplitude is H-polaroid is prepared by Evidence for the wave nature of light cannot be obtained from Which radiation in sunlight, causes heating effect In the propagation of light waves, the angle between the direction of vibration and plane of polarization is In Young’s experiment, one slit is covered with a blue filter and the other (slit) with a yellow filter. Then the interference pattern
