Light waves

  1. Jan 16, 2006 #1
    hey found this question in my text book...
    explain using interferance why a super thin film is transparent or invisible in transmitted light but seems to be opaque when viewed with reflected light. Draw a diagram for your solution. any ideas?? i really have no idea. thanx for your time though.

    HINT: How much reflected light would there be if all the light were transmitted? :)

    if all the light went through wouldnt it be "invisible" but how could it be opaque?, like i guess some reflected rays and incident rays would create destructive interferance, but wouldnt you still be able to see through????

    Think of what your looking for. (Light thats reflected back or light that goes through)
