Introduction: The purpose of this lab is to observe the optical concepts known as diffraction and interference. Theory: Light is a wave and thus has a wavelength. White light consists of a continuous spectrum of all visible colors (ROYGBIV), each with a distinct wavelength. Lasers have one specific wavelength; the laser used in this lab has He-Ne gases, which produce a wavelength of approximately 634 nm. In this experiment, we will look at different slit combinations …
