The two slits are

1\,mm

apart from each other and illuminated with a light of wavelength

5 \times {10^{ - 7}}\,m

. If the distance of the screen is

1\,m

from the slits, then the distance between third dark fringe and fifth bright fringe is

View answer and explanation

Correct option: C

1.25\,mm

Option C (

1.25\,mm

) is correct because it is calculated by finding the positions of the third dark fringe and fifth bright fringe and then subtracting them.

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
