Young’s Double Slit Experiment
PHXII10:WAVE OPTICS

368059 In Young’s double slit experiment, the ratio of intesities of bright and dark bands is 16 which means

1 The ratio of their amplitude is \(5:3\)
2 Intensities of individual sources are 25 and 9 units respectively
3 The ratio of their amplitudes is 4
4 Intensities of individual sources are 4 and 3 units respectively

368060 Assertion :
Given, In Young's double slit experiment the two slits are at distance \(d\) apart. Interference pattern is observed on a screen at distance \(D\) from the slits. At a point on the screen when it is directly opposite to one of the slits, first dark fringe is observed.
Reason :
The wavelength of wave is proportional to square of distance of two slits.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.

368061 In a Young’s double slit experiment, a student observes 8 fringes in a certain segment of screen when a monochromatic light of \(600\;nm\) wavelength is used. If the wavelength of light is changed to \(400\;nm\) , then the number of fringes he would observe in the same region of the screen is
