Problem
Three transparent solids—X, Y, and Z—have indices of refraction 1.20, 1.40, and 1.60, respectively. Identical green photons enter each solid from air. Which statement best compares their speeds and wavelengths inside the materials?
(a) Photons move fastest and have the shortest wavelength in X.
(b) Photons move slowest and have the longest wavelength in Z.
(c) Photons move fastest and have the longest wavelength in X.
(d) Photons move fastest and have the longest wavelength in Z.
