That blue laser is definitely my all time favorite laser that I've owned...the actual wavelength is probably near 480nm considering the spectrometer tests that were done on this type of laser diode.that light blue pen laser is like my dream laser. Its so pretty !!! I also just realized i need to go back to college. Thats probably easy math more most on here but its over my head. :cryyy:
Pretty amazing video none the less
I would assume this would be a standard thing, and according to some websites is 1.6 microns. If that's true, my measurement (~1.5 micron) was close, but definitely not perfect. Oh well, this experiment isn't meant to be perfect, just to show that cool science can be done with household items.This is probably a dumb question, but is the distance between slits on the particular CD that you are using a "standard" width?
In other words, would a different CD have the same distance between slits?
