A laser light of wavelength 500 nm falls on a diffraction grating that has 2500 slits/cm. What is the slit spacing?

A

Explanation:

Given that the diffraction grating has 2500 slits/cm

And the wavelength of light = 500nm

The wavelength of light has no effect on the calculation of the split spacing in this question. So,

The slit spacing will be :

Slit in m ÷ number of slits

Slit spacing = 0.01/2500

Slit spacing = 4 × 10^-6 m

Therefore, option A is the correct answer.

explanation:

the masses of the objects and the distance between them

it doesn't. it was imagined up in the middle ages.
