A Fabry-Perot etalon has a peak transmission at 500 nm corresponding to an order n nd a spectral width of 1 nm for light at normal incidence. Suppose the etalon is rota pes the peak transmission shift to the red or blue? In addition to a calculation, exp hy in qualitative terms (with a sketch if needed). By how far would you have to rotate alon to shift the transmission peak by 1.5 nm? Assume the refractive index inside

Transcribed Image Text:4. A Fabry-Perot etalon has a peak transmission at 500 nm corresponding to an order m=3,
and a spectral width of 1 nm for light at normal incidence. Suppose the etalon is rotate%3;
does the peak transmission shift to the red or blue? In addition to a calculation, explain
why in qualitative terms (with a sketch if needed). By how far would you have to rotate the
etalon to shift the transmission peak by 1.5 nm? Assume the refractive index inside the
etalon is 1.6.
