What type of wave propagates along a surface between media?

Longitudinal wave

Surface wave

Transverse wave

Which quantity sets the speed of a wave on a string with tension F and linear density μ?

v = F/μ

v = sqrt(F/μ)

v = μ/F

What is the fundamental frequency for a string of length L with wave speed v?

f1 = 2L/v

f1 = v/L

f1 = v/(2L)

In standing waves, what are the points that do not move called?

Nodes

Antinodes

Crests

What is the lowest standing wave frequency called?

Overtone

Fundamental frequency

Harmonic

Which term describes energy transfer without the net transport of matter?

Mass transport

Particle motion

Wave energy transfer

What is the displacement function for a right-traveling sinusoidal wave on a string?

y(x,t) = A sin(kx + ωt)

y(x,t) = A cos(kx + ωt)

y(x,t) = A cos(kx - ωt)

What happens to energy in a standing wave’s nodes?

Maximum energy transfer

No energy transfer at nodes

Energy leaks out

Which principle explains the speed of fluids through a height difference?

Torricelli's principle

Pascal's law

Bernoulli's principle

What is the ratio of the output pressure fluctuation to displacement amplitude called?

Pressure amplitude

Displacement amplitude

Velocity amplitude
