# shows the light intensity on a screen behind a double slit. The slit spacing is and the screen is behind the slits. What is the wavelength (in ) of the light?

The light's wavelength is

See the step by step solution

## Step: 1 wavelength light:

The wavelength of visible light is to , and this is where we understand about the widths of multiple colors in the visible spectrum of light.

## Step: 2 Finding the width:

As per the diagram,since the width of four fringes is , the width of one fringe will be

We understand that the fringe thickness in the double-slit experiment is calculated as

## Step: 3 Obtaining the wavelength value:

The wavelength by
