Question:
A glass binocular lens (nglass = 1.50) is coated with a thin layer of magnesium fluoride MgF2 (nf = 1.38).
- If the coating is to cause destructive interference in reflected light for l = 560 nm (corresponding to the peak of the solar spectrum), what should its minimum thickness be?
- At what two wavelengths closest to 560 nm does the coating cause constructive interference in reflected light?
- Is any visible light reflected? Explain your answer
