Diffraction Grating Experiment: Wavelength of Laser Light
Light propagates, or travels, in waves. Waves have two main properties: frequency and wavelength. When you know one, it’s pretty easy to calculate the other.
When light waves overlap they create interference, and the patterns caused by this can be used to determine the wavelength of light. Conduct this cool diffraction grating experiment to determine the wavelength of laser light emitted from any laser pointer.
