A ray of white light in air incident on the left face of a glass prism.
A ray of white light in air incident on the left face of a glass prism.
A narrow beam of white light traveling in air is incident on the left face of a transparent glass prism at an angle of incidence \(\theta_1 > 0^\circ\). The glass exhibits chromatic dispersion such that the index of refraction of the glass is greater for violet light (\(\lambda_0 \approx 400\text{ nm}\)) than for red light (\(\lambda_0 \approx 700\text{ nm}\)), so that \(n_{\text{violet}} > n_{\text{red}}\). Which of the following statements correctly compares violet light to red light inside the prism, and provides the correct physical justification?
