8th Grade Waves Review

Front

What is the definition of wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What does amplitude represent in a wave?

Back

Amplitude is the maximum distance that points on a wave, such as the crest or trough, move from their rest position.

Front

What is a compressional wave?

Back

A compressional wave, also known as a longitudinal wave, is a type of wave where the particles of the medium move parallel to the direction of the wave's travel.

Front

What happens when a wave hits an object it cannot pass through?

Back

When a wave hits an object it cannot pass through, it will diffract, or bend around the object.

Front

How do you calculate the wavelength of a wave?

Back

Wavelength can be calculated using the formula: Wavelength = Speed / Frequency.

Front

What is the frequency of a wave?

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz).

Front

What is the relationship between speed, frequency, and wavelength?

Back

The relationship is given by the formula: Speed = Frequency x Wavelength.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, particles move perpendicular to the direction of the wave, while in longitudinal waves, particles move parallel to the direction of the wave.
