a beam of laser light, wavelength 725.3 nm in air is incidnet on a block of unknown transparent material at an angle of 27 degrees. Its wavelength in the new equilibrim is 562 nm.   1. Find the angle of refraction in the material 2. Find the index of refraction of hte material

A narrow beam of light containning red (650nm) and blue (480nm) wavelength travels through a 1.00 cm thick flat piece of crown glass and back to air again. The beam strikes at a 30 degree incident angle. A) At what angles do the 2 colors emerge. B) what distance are red and blue separated when they emerge? Index refraction of crown glass (1.47)

Ꮎ air α prism -B air glass White light is incident from air onto a triangular prism at an angle denoted with respect to the normal. It refracts into the prism then into glass then exits into the air. The prism has an index of refraction of 1.49 for red light and 1.52 for violet light. The glass has an index of refraction of 1.61 for red light and 1.64 for violet light. What is the angular separation (dispersion angle) of the two noted colors after leaving the glass? Take nair = 1.00 for all wavelengths. SOLVE IN TERMS OF 0, a and B!!!
