# A diffraction grating having diffracts visible light at . What is the light's wavelength?

The wavelength of sunshine is

See the step by step solution

## Step: 1 Finding the grating spacing:

The constant value of grating is ,the spacing by

## Step: 2 Equating the equation:

In equation of grating,the light diffraction light wavelength by

## Step: 3 Obtaining the wavelength value:

From expression of wavelength

As we're seeing, there should only be one value of that corresponds to a wavelength within the visible region and therfore the will be ,The wavelength are .
