Homework Help: Physics

Posted by Samantha on Saturday, March 20, 2010 at 8:46pm.

The refractive index of a medium changes with the wavelength of incident light. Typically, the shorter the wavelength the larger the refractive index.

Fused quartz has a refractive index of 1.47 for indigo light of 400 nm in wavelength, and a refractive index of 1.46 for green light of 550 nm in wavelength.

If rays of indigo and green light enter fused quartz from air, making an angle of 45, the angle that separates two rays as they travel through the fused quartz is closest to ...
