Wave optics- thin films
a thin film 4x10-5cm thick is illuminated by white light normal to its surface. its index of refraction is 1.5. what wavelengths within the visible spectrum will be intensified in the reflected beam? (visible light is taken to be wavelengths between 390 to 700nm)
question: choose the thin film equation for the type of interference and number of phase changes of this situation and solve for the wavelength(s) in the visible range. (may need to evaluated multiple m's)
