2024 WAVES Review

Front

What is frequency in the context of waves?

Back

Frequency is the number of waves that pass a point in one second.

Front

What is the relationship between energy and wavelength in waves?

Back

Generally, waves with shorter wavelengths have higher energy.

Front

What type of wave is a sound wave?

Back

A sound wave is a longitudinal wave in which the particles of the wave move in a direction parallel to the wave motion.

Front

What is amplitude in wave terminology?

Back

Amplitude is the maximum distance that the particles of a wave move from their rest position.

Front

How do you differentiate between transverse and longitudinal waves?

Back

In transverse waves, particles move perpendicular to the wave motion; in longitudinal waves, particles move parallel to the wave motion.

Front

What is the speed of a wave?

Back

The speed of a wave is the distance it travels in a given amount of time.

Front

What does it mean if two waves are in phase?

Back

Two waves are in phase if their crests and troughs align, resulting in constructive interference.

Front

What is the principle of superposition in wave theory?

Back

The principle of superposition states that when two or more waves overlap, the resulting wave displacement is the sum of the individual displacements.

Front

What is a wave pulse?

Back

A wave pulse is a single disturbance that travels through a medium.

Front

What is the difference between constructive and destructive interference?

Back

Constructive interference occurs when waves combine to make a larger wave, while destructive interference occurs when waves combine to make a smaller wave or cancel each other out.
