Two parallel laser beams, one blue (450 nm450\text{ nm}450 nm in air) and one red (650 nm650\text{ nm}650 nm in air), are incident at the same non-zero angle of incidence θi \theta_i\,θi from air onto a flat glass block, as shown in the diagram.
Inside the glass block, the blue beam is refracted more than the red beam. Which statement correctly describes the behavior of the two laser beams?
The frequency of both lasers decreases upon entering the glass block, with the blue laser experiencing a larger decrease.
The ratio of the speed of the red laser to the speed of the blue laser inside the glass block is less than 1.01.01.0.
The speed of the blue laser inside the glass block is less than the speed of the red laser inside the glass block.
The angle of refraction inside the glass block is larger for the blue laser than for the red laser.
