A Beka: Physics Quiz 22

Constructive

If two waves' amplitudes increase when they collide, the waves have undergone ? interference.

Frequency

The ? of a wave is defined as the number of waves that pass a given point per unit time.

true

The angles of incidence and reflection are equal for any type of reflection.

Superposition

The principle of ? states that when two or more waves are traveling simultaneously through the same point in a medium, the displacement of any particle at that point is the algebraic sum of the displacements that would be caused by the waves separately.

Wavelength

What is defined as the distance from any point on a wave to the corresponding point on the next wave?

Reflection

What is defined as the turning back of a wave at an interface?

false

When a wave passes through a narrow opening, its diffraction is most pronounced when the opening is roughly equivalent to half a wavelength.

v=√(F/μ)

Which of the following determines wave velocity using mass per unit length?

Longitudinal

A ? wave is composed of both compression and rarefaction pulses.

Node

any point where the medium remains undisturbed because of wave interference
