A simple way to measure the wavelength of light by taking measurements in the lab.

1. Measuring the Wavelength of Light with a Double Slit
A laser will diffract and interfere when shone through a double slit. A series of dark and bright fringes can be measured on a screen which will then allow you to calculate the wavelength of light.
Be careful with the laser. Do not look at the beam or any reflected light from a shiny surface.
