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.

Question

2. The same laser is now fired at a screen with a single slit of width 0.1 mm, again 2.0 m from the
screen behind it.
a) Relative to the central maximum, where will the first four dark fringes be located on the screen.
Write your answers in mm.
b) Sketch the pattern of bright and dark fringes.

A pinhole camera has a small circular aperture of diameter D. Light from distant objects passes through the aperture into an otherwise dark box, falling on a screen at the other end of I lie box. The aperture in a pinhole camera has diameter D = 0.600 mm. Two point sources of light of wavelength 550 mil are at a distance L from the hole. The separation between the sources is 2.80 cm, and they are just resolved by the camera. What is I?
One leg of a Michelson interferometer contains an evacuated cylinder of length L, having glass plates on each end. A gas is slowly leaked into the cylinder until a pressure of 1 atm is reached.

Hint: The fringe shifts occur because the wavelength of the light changes inside the gas-filled tube.
