Questions and Answers
Explain the difference between longitudinal and transverse waves, and provide examples of each.
Longitudinal waves propagate in the same direction as the energy transfer, while transverse waves have motion perpendicular to the direction of energy transfer. An example of a longitudinal wave is sound waves traveling through air, while an example of a transverse wave is waves on a string or electromagnetic waves like light.
What is the unit of measurement for frequency, and how is it related to hertz?
The unit of measurement for frequency is hertz (Hz), which represents the number of cycles per second. One hertz is equivalent to one cycle per second.
Can a wave be both longitudinal and transverse? Explain your answer.
No, a wave cannot be both longitudinal and transverse at the same time. This is because the motion of the medium in a longitudinal wave is parallel to the energy transfer, while the motion of the medium in a transverse wave is perpendicular to the energy transfer.
