Question 2

Period: [___]

Revolt · Accepted Answer

both longitudinal and transverse

Question 3

Wavelength: [___]

Revolt · Accepted Answer

both longitudinal and transverse

Question 4

Which wave, A or B, has lower energy?

Revolt · Accepted Answer

A, because it has a lower amplitude

Question 5

Tara prepared a report to show how the amplitude of waves affects the energy of waves. Is her graphical representation correct? Why or why not?

Revolt · Accepted Answer

No. The graph is incorrect because it shows energy decreasing as amplitude increases. A wave’s energy increases as its amplitude increases.
