Wave Behaviour

Consider the energy transformations in a frictionless mass-spring system shown in the diagram. Which statement correctly identifies the energy state at the equilibrium position?

In a system performing simple harmonic motion, at which position is the magnitude of the velocity of the object at its maximum?

A particle oscillates with a frequency of $2.5\ \text{Hz}$. What is the time period $T$ of the oscillation?

What is the period of a wave that has a frequency of $100\text{ Hz}$?

If 10 crests of a water wave pass a buoy in 2 seconds, what is the frequency of the wave?

What is the highest point on a transverse wave called?

A transverse wave pulse travels along a string and is reflected from a 'fixed' boundary (a point where the string is tied to a wall). What is the phase change of the reflected pulse?

Under which of the following conditions is the diffraction of a wave through a single slit most significant?

When a water wave in a ripple tank moves from a deep region into a shallower region, which property of the wave remains unchanged?

In a stationary wave, the points that never move are called:

The speed of sound in a pipe is $340 \text{ m s}^{-1}$. If the length of an open pipe is $1.0 \text{ m}$, what is the frequency of the first harmonic?

What happens to the wavelength of the fundamental mode of a string if its length is doubled?

Christian Doppler, the namesake of the effect, first proposed it in relation to which phenomenon?

When a light source moves very fast away from an observer, the frequency of the light shifts toward which part of the electromagnetic spectrum?

If a car is moving away from you at $30\text{ m/s}$ and honking its horn, the frequency you hear is $400\text{ Hz}$. If the car speeds up to $50\text{ m/s}$ away from you, the frequency you hear will be:
