Physics U6 Review

Front

What is the frequency of a wave?

Back

The number of oscillations or cycles that occur in one second, measured in Hertz (Hz).

Front

If a wave oscillates 15 times in 3 seconds, what is its frequency?

Back

5 Hz

Front

What is the wavelength of a wave?

Back

The distance between two consecutive points that are in phase on a wave, such as crest to crest or trough to trough.

Front

If a wave is 40 meters long, what is its wavelength if it oscillates 15 times in 3 seconds?

Back

20 m

Front

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

Back

Wave speed = frequency x wavelength.

Front

What is a standing wave?

Back

A wave that remains in a constant position, typically formed by the interference of two waves traveling in opposite directions.

Front

How many wavelengths are in a standing wave that is 40 meters long?

Back

1.5 wavelengths.

Front

What type of wave is used in medical imaging to look at bones?

Back

Electromagnetic waves with very short wavelengths, such as X-rays.

Front

What is the formula to calculate frequency?

Back

Frequency (f) = Number of oscillations / Time (in seconds).

Front

What is the unit of measurement for frequency?

Back

Hertz (Hz), which is equivalent to one cycle per second.
