SUMMARY
The discussion focuses on calculating the frequency of red light in air and its wavelength in glass. Given the wavelength of red light as 560 nm and the speed of light in glass as 1.96 x 108 m/s, the frequency in air can be determined using the formula f = c/λ, where c is the speed of light in a vacuum (3 x 108 m/s). The wavelength in glass is calculated using the refractive index, with the formula λglass = λair/n, where n is the refractive index of glass (1.52).
