## How do you find the distance between waves?

For calculating the distance that sound travels; distance = velocity x time.

## What do we call the distance between a spot on a wave to the same spot on the next wave?

Wavelength: The distance from a certain point on one wave to the same point on the next wave (e.g. distance between two consecutive wave crests or between two consecutive wave troughs).

**What is the distance between the same point of 2 waves called?**

Wavelength, distance between corresponding points of two consecutive waves. “Corresponding points” refers to two points or particles in the same phase—i.e., points that have completed identical fractions of their periodic motion.

**What is called wave height?**

As is shown on the figure, wave height is defined as the height of the wave from the wave top, called the wave crest to the bottom of the wave, called the wave trough. The wave length is defined as the horizontal distance between two successive crests or troughs.

### Is the highest point a wave can reach?

The highest surface part of a wave is called the crest, and the lowest part is the trough. The vertical distance between the crest and the trough is the wave height. The horizontal distance between two adjacent crests or troughs is known as the wavelength.

### What is the wave speed?

The wave speed, v, is how fast the wave travels and is determined by the properties of the medium in which the wave is moving. If the medium is uniform (does not change) then the wave speed will be constant. The speed of sound in dry air at 20 C is 344 m/s but this speed can change if the temperature changes.

**How is the wavelength of a wave measured?**

The wavelength of a wave is the distance between a point on one wave and the same point on the next wave. It is often easiest to measure this from the trough of one wave to the crest of the next wave.

**How many waves pass one point during one second?**

Frequency describes how many waves pass one point during one second. The units for frequency are hertz. Traveling through the air, a music note with a frequency of 261.6 hertz (middle C) pushes air molecules back and forth 261.6 times every second.

## How is the period of a wave measured?

Period. The period of a wave is the time taken for one wave to be produced. It is also the time taken for one whole wave to pass a point. Period is measured in seconds.

## Which is true about the amplitude of a wave?

The amplitude of a wave is its maximum disturbance from its undisturbed position. It is important to note that the amplitude is not the distance between the top and bottom of a wave. The wavelength of a wave is the distance between a point on one wave and the same point on the next wave.
