Problem 2For wavelengths in the visible spectrum, the index of refraction of a cer-tain type of crown glass can be approximated by the relation n(1) = 1.5255 +(4825 nm²)/a².b. Find the phase velocity, in this glass, for a pulse with frequency com-ponents centered around 500 nm.c. Find the group velocity, in this glass, for a pulse with frequency com-ponents centered around 500 nm.

Wavelength, λ=500nm=500×10-9mSpeed of light, c=3×108m/s The index of refraction is specified as:…
