Problem
When passing through a glass prism, violet light bends more than red light. Which statement best explains this observation?
(a) Violet light carries more energy than red light, so the additional energy causes it to change direction more in the prism.
(b) Violet light has a shorter wavelength than red light, so its speed in glass is reduced more, causing greater refraction.
(c) Violet light interacts more strongly with the prism’s edges, producing greater diffraction that appears as additional bending.
(d) Violet light has a lower frequency than red light, making it slower in glass and therefore bend more.
