Front

What sound characteristic is indicated by a low pitch and quiet volume?

Back

A sound that is both low in pitch and quieter is represented by Wave C.

Front

Do radio waves and gamma rays travel at the same speed?

Back

Yes, they travel at the same speed.

Front

In an experiment, what is the dependent variable when testing how mass affects distance rolled?

Back

The dependent variable is the distance traveled by the ball.

Front

Define wavelength in the context of waves.

Back

Wavelength is the distance between successive crests of a wave.

Front

What is frequency in wave terminology?

Back

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

Front

Explain the relationship between wavelength and frequency.

Back

Wavelength and frequency are inversely related; as wavelength increases, frequency decreases.

Front

What is the speed of electromagnetic waves in a vacuum?

Back

Front

What is the formula to calculate the speed of a wave?

Back

The speed of a wave is calculated using the formula: Speed = Wavelength × Frequency.
