Calculate th e wavelength of ligh t used in an interference experiment...
Given: fringe with β = 0.03 cm, D = 1 m = 100 cm
Distance between images of the source = 0.8 cm.
Image distance v = 80 cm
Object distance = u
Using mirror formula, 
⇒ u = 20 cm
Magnification,

Calculate th e wavelength of ligh t used in an interference experiment...
To calculate the wavelength of light used in the interference experiment, we can use the formula:

λ = (d * D) / L

where λ is the wavelength, d is the fringe width, D is the distance between the slits and the eyepiece, and L is the distance between the images of the virtual source.

Given:
Fringe width (d) = 0.03 cm
Distance between slits and eyepiece (D) = 1 m = 100 cm
Distance between images of virtual source (L) = 0.8 cm

Plugging in these values into the formula, we get:

λ = (0.03 cm * 100 cm) / 0.8 cm
λ = 3.75 cm

Therefore, the wavelength of light used in the interference experiment is 3.75 cm.
