Chapter 2- Properties Of Waves

Question 0

Wavelength

Answer 0

The distance over which the wave’s shape repeats.

Wavelength is measured by the distance from one point on a wave to an identical point later on the wave.

Question 1

Amplitude

Answer 1

A measure of how far particles in the medium move away from their normal rest position.

Question 2

Wave Period (usually called period)

Answer 2

The time required for one cycle. You can measure the period by finding the time for one full pattern of a wave to pass a given point.

Question 3

Frequency

Answer 3

Tells you how many cycles occur in an amount of time, most commonly one second.

Question 4

Hertz

Answer 4

Frequency is measured by hertz. One hertz is equal to one cycle per second. If ten peaks pass each second, the frequency is 10 hz.

Question 5

Wavefronts

Answer 5

The peaks can be drawn as as shapes, such as circles or spheres.

Question 6

Wave Speed

Answer 6

The speed at which a wave travels. It depends on the properties of the medium.
