In young's double slit experiment with a source of light of wavelength

6320\,\mathop {\text{A}}\limits^ \circ

, the first maxima will occur when

View answer and explanation

Correct option: C

Path difference is

6320\,\mathop {\text{A}}\limits^ \circ

Option C is correct. The first maxima occurs when the path difference is equal to one wavelength, which is

6320\,\mathop {\text{A}}\limits^ \circ

.

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
