WAVESPEED PRACTICE

Front

What is wave speed?

Back

Wave speed is the distance a wave travels per unit of time, typically measured in meters per second (m/s).

Front

What is the relationship between wavelength and frequency?

Back

As the wavelength increases, the frequency decreases, and vice versa, when wave speed is constant.

Front

What is the formula for calculating wave speed?

Back

The wave speed (v) is calculated using the formula v = λf, where λ is the wavelength and f is the frequency.

Front

What happens to wave speed when the medium changes?

Back

Wave speed can change when the medium changes, depending on the properties of the new medium.

Front

What is a medium in the context of waves?

Back

A medium is the substance through which a wave can travel, such as air, water, or solid materials.

Front

How does increasing wavelength affect wave speed in a given medium?

Back

In a given medium, increasing the wavelength does not affect the wave speed; it remains constant.

Front

What is frequency in relation to waves?

Back

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

Front

If a wave has a frequency of 10 Hz and a wavelength of 2 m, what is its speed?

Back

The speed of the wave is 20 m/s, calculated using v = λf (v = 2 m * 10 Hz).

Front

What is the unit of measurement for wavelength?

Back

The unit of measurement for wavelength is meters (m).

Front

What is the effect of frequency on wavelength if wave speed is constant?

Back

If wave speed is constant, an increase in frequency results in a decrease in wavelength.
