Young's doublt slit experiment - Systematic and random errors - URGENT!
Can anybody think of any other systematic and/or random errors for young's double slit experiment when using it calculate the wavelength of a light source? I have an inclass prac write up tomorrow and i can't think of any others, if you guys can think of any THEN PLEASE HELP, THANKS!
Random
1. Parallax error – distance from cross hairs to screen -
2. Parallax error – reading from vernier caliper
3. Widely spaced fringes of light of interference
4. Light entering from beneath cloth – interference - lower intensity light – less precise measurement
Systematic
1. Formula depends on the angular separation of the double slits to be extremely small, <<1 degree – so it is an approximation, hence an error
