Kent Said:

thin film physics question?

We Answered:

The formula t=(m+1/2)lambda seem right. The light you see in air is 475nm, but the wavelength of light in the silicon thin film is shorter by lamdba/4.5. You want the thickness of the film to correspond to 1/2 multiples of the wavelength WITHIN the film. So use that new wavelength and the formula.

Different thicknesses can be found by using different m's: m=0, 1, 2.
