Two straight narrow slits separated by a distance 0.08m mare illuminated by a source of light of wavelength

5460\,\mathop \mathrm{A}\limits^ \circ

. If the fringes are measured with a micrometer eyepiece it is found that 2 fringes occupy a distance of 10.92mm. The distance of the eye piece from the slits is

View answer and explanation

Correct option: A

0.8 m

Option A (0.8 m) is correct because it is calculated using the fringe width formula and the given parameters.

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
