There is a thin film of soap bubble of thickness d on air with a refractive index of n. When an incident light of wavelength is falling on the soap bubble it is creating a dark fringe and when the wavelength is falling it is creating a bright fringe of the same order at the same position on screen. Prove that the order of the fringe is From the above relation find the thickness of the soap bubble of refractive index 1.35 which is creating a bright fringe for 370nm and a dark fringe for 500nm.

Diffraction of light

In physics, the term diffraction is defined as the bending of light around the corners of the obstacle. As a light ray passes by an aperture, it bends around the edges or through slits, it spreads out through a narrow opening. The diffracted light will produce fringes of bright and dark or colored bands which are labeled as a diffraction pattern.
