In Young's experiment of Figure 2 the wavelength λ = 500 nm, the distance between the slits is 0.4 mm. The screen on which the interference bangs appear is 50 cm from the slits. What is the distance from the second maximum to the center of the interference figure? Assume the angle of the position of the maximum to be small.

Interference of light
The phenomenon, in which alternate bright and dark bands (fringes) are produced as a result of superposition of two monochromatic light waves having same wavelength but a constant phase difference proceeding in the same direction, is called interference of light.
Young's Experiment:
In 1802, Thomas Young demonstrated the interference of light experimentally. The experiment gave a deadly blow to the corpuscular theory of light. The experiment leads to the conclusion that light has wave nature.
