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

A monochromatic light passes through two narrow slits that are 0.03 mm apart. The second
order bright fringe is observed at an angle of 0 = 5.2° on a screen 1.50 m from the slits.
Compute the

(i)
wavelength of the light,
(ii)
distance between the second and fifth order of bright fringe, and
(iii)
angle of the interference pattem produced by the fifth order.
