In Young's double slit experiment, the width of fringe obtained from a source of light of wavelength

5000\mathop {\text{A}}\limits^ \circ

is 3.9

\mathrm{mm}

. if the apparatus is immersed in a liquid of

\mu=1.3

, the fringe width will be

View answer and explanation

Correct option: A

3

The correct answer is A (3) because the fringe width is inversely proportional to the refractive index of the medium.

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
