Young's Double Slit Experiment

Practice Questions:

Question 1: difficult

In the Young’s double slit experiment using a monochromatic light of wavelength λ , the path
difference ( in terms of an integer n) corresponding to any point having half the peak
intensity is

1. (2n +1) λ/2

2. (2n +1) λ/4

3. (2n +1) λ/8

4. (2n +1) λ/16

Question 2: difficult

White light is used to illuminate the two silts in a Young’s double slit experiment. The separation between the slits is b and the screen is at a distance d (> > b) from the slits. At a point on the screen directly in front of one of the slits, certain wavelengths are missing. Some of these missing wavelengths are :

1. \[\lambda=\frac{b^{2}}{d}\]

2. \[\lambda=\frac{2b^{2}}{d}\]

3. \[\lambda=\frac{3b^{2}}{d}\]

4. \[\lambda=\frac{2b^{2}}{3d}\]
