What is meant by diffraction of light? Write the conditions for maxima and minima of diffraction pattern in terms of the wavelength of light used for the diffraction at single slịt.

Explanation

Diffraction of light : The phenomenon of bending of light waves around the sharp edges or corners of an obstacle.
Condition for maxima is given by
` theta = (2n +1) lamda/(2a)`
where `n=1,2,3,…….`
Condition for minima is given by
` theta = (2n ) ( lamda )/( 2a) `
where `n=1,2,3,........`
