The purpose of this lab is to determine the wave length for Helium Neon laser.
Lasers have many uses in our lives.
Lasers can be used to read CD's. Also it can be used for to cut through steel and it is also used for eye surgery. In this lab we are doing something simple with a laser, find out the wave length for a Helium Neon laser. First of all in this lab the following formulas need to be known.
