Answer:
The wavelength of light is 533 nm.
Explanation:
It is given that,
Width of a single slit, 
Light has its third minimum at an angle of 23.3° when it falls on a single slit. For destructive interference, the equation for minima is given by:
Here, n = 3
So, the wavelength of the light is 533 nm. Hence, this is the required solution.
