Coherent Monochromatic light of wavelength H in air is incident on two narrow slits, the centers of which are 2 mm apart. The interference pattern is observed on a screen 5.0 m away is represented on a graph of light intensity I as a function of position x on the screen. a) What property of light does this interference experiment demonstrate? b) At point P in the diagram, there is a minimum in the interference pattern. Determine the path difference between the light arriving at this point from the two slits. (P is 1.5 wavelengths up from 0 on the screen) c) Determine the wavelength of light.
Edit: The first answer is pretty simple. A) Property of Light is Interference. Working on the others... Edit2: After about 30 mins I think I've found the answer to C C) Wavelength = 10x6^-4 Although visible light ranges from 400-700-ish nanometers (10^-9) in wavelength, so this light must have a much shorter wavelength than visible light...or I did my math wrong!
