Answer:
The wavelength of the light is
m
Step-by-step explanation:
Given :
Distance between two slit
m
Distance of screen
m
Distance between central fringe to 5th bright fringe,
m
From the formula of interference,

Where
≅
we put


Where
5 ( given in question )
Now we have to find wavelength of the light,


m
Therefore, the wavelength of the light is
m
