Students were in charge of presenting information they found about the various types of waves to their group. Carl told his group “this wave can be transverse, travel through solids, and has a high frequency”. Four different students responded with the questions shown. Which student asked a question that would allow students to determine if Carl is talking about an electromagnetic wave or a mechanical wave?

A.
Rebecca: “What is the amplitude of the wave?”

B.
Amy: “Is the wave carrying energy or matter?”

C.
Hanna: “Can the wave travel through something liquid too, like a milkshake?”

D.
