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

In a double-slit experiment, the distance between slits is 5.0 mm and the slits are 1.0 m from the screen.
Two interference patterns can be seen on the screen: one due to light of wavelength 480 nm, and the other
due to light of wavelength 600 nm. What is the separation on the screen between the third-order (n = 3)
bright fringes of the two interference patterns?

Coherent light rays of wavelength strike a pair of slits separated by distance d at an angle 1, with respect to the normal to the plane containing the slits as shown in Figure P27.14.

Show that the angle 2 is given by 2=sin1(sin1md) where m is an integer.
