 # Suppose pure-wavelength light falls on a diffraction grating. What happens to the interference pattern if the same light falls on a grating that has more lines per centimeter? What happens to the interference pattern if a longer-wavelength light falls on the same grating? Explain how these effects are consistent in terms of the relationship of wavelength to the distance between slits. ### College Physics

## Suppose pure-wavelength light falls on a diffraction grating. What happens to the interference pattern if the same light falls on a grating that has more lines per centimeter? What happens to the interference pattern if a longer-wavelength light falls on the same grating? Explain how these effects are consistent in terms of the relationship of wavelength to the distance between slits.

Expert Solution
To determine

The change in interference pattern when light falls on a grating with more lines per centimeter or when light with longer wavelength falls on it.

### Explanation of Solution

Introduction:

We have grating equation, sinθ=nNλ

Where,

n order of the spectrum N number of lines per centimeter on grating

λ wavelength of incident light   θ
