Question

"The Dark Side of the Moon" (1973) by Pink Floyd cover is a pop culture icon. By making the appropriate measurements on the picture and assuming the light begins and ends in vacuum: (a) determine the reflective index (n) of the prism. Does the second refraction indicate the same refractive index? (b) Make measurements on the picture to determine if the dispersion is exaggerated or depicted for a real material. (c) Why or why not the red part of the rainbow should be on the top or if it makes more physical sense for it to be on the bottom?

Explanation / Answer

(a)refractive index can be determined by optical spectrometer using angle of minimum deviation and Angle of prism (b) The dispersion looks exaggerated. (c) The red part of rainbow is at the top because amount of dispersion is inversely proportional to wavelength so red is least deviated and is in the top. AND MAN I LOVE PINK FLOYD. THE BEST PSYCHEDELIC BAND EVER.
