1. The problem statement, all variables and given/known data The glass prism has an index of refraction that depends on the wavelength of the light that enters it. The index of refraction is 1.44 for light of wavelength 7.245 × 10−7 m in a vacuum and 1.79 for light of wavelength 4.433 × 10−7 m in vacuum. A beam of white light is incident from the left, perpendicular to the ﬁrst surface, as shown in the ﬁgure, and is dispersed by the prism into its spectral components. Determine the frequency of the 7.245×10−7 m light in the glass. Answer in units of Hz 2. Relevant equations c = λf 3. The attempt at a solution Alright so I calculated the frequency to be 5.03125e-7 (this is correct), so I just plugged this into the formula 3*10^8/5.03125e-7 and got 5.96*10^14 m I thought I did this correctly. Did I do something silly?
