Astronomers observe the chromosphere of the Sunwith a filter that passes the red hydrogen spectral line of wave-length 656.3 nm, called the H line. The filter consists of atransparent dielectric of thickness d held between two par-tially aluminized glass plates. The filter is kept at a constanttemperature. (a) Find the minimum value of d that will pro-duce maximum transmission of perpendicular H, light if thedielectric has an index of refraction of 1.378. (b) If the tem-perature of the filter increases above the normal value increas-ing its thickness, what happens to the transmitted wavelength?(c) The dielectric will also pass what near-visible wavelength?One of the glass plates is colored red to absorb this light.

(a). The thickness of the dielectric can be calculated as follows,

A beam of light with wavelength 440 nm in air hits a thin piece of glass 10.28 microns thick (with refractive index 1.55) at an angle of 40.8 degrees to the normal. What is the path difference between the two reflections from the layers of the glass, in wavelengths? [Note to get the phase shift we multiply this number by 2π, but this is modulo 2π, i.e. any integer number of wavelengths are 2π phase shifts, equivalent to no phase shift... basically in terms of phase we only really need the non-integer part of your answer. Note also that for the phase shift we would need to add a π for the reflection off the glass-air interface.]
