Question
In experiment 1, a periodic water wave is incident on a boundary between two regions of different depth. The waves on the water surface are generated by a dowel moving back and forth at a steady rate. The diagram above shows both wavefronts and rays for the incident and transmitted waves.
In experiment 2, two changes have been made to experiment 1: the rate at which the dowel is moved back and forth is twice that in experiment 1 and the depth of water in region 1 is increased such that the propagation speed of the incident wave is twice that in experiment 1.
Compare each of the quantities below that describe the propagation of the incident wave in experiment 2 to the corresponding quantity in experiment 1.
The propagation speed of the incident wave in experiment 2 is:
greater than that in experiment 1
less than that in experiment 1
equal to that in experiment 1
Not enough information to answer the question.
The wavelength of the incident wave in experiment 2 is:
greater than that in experiment 1
less than that in experiment 1
equal to that in experiment 1

The frequency of the incident wave in experiment 2 is:
greater than that in experiment 1
less than that in experiment 1
equal to that in experiment 1
