The speed of the wave is equal to the frequency multiplied by the wavelength. Given that four wave crests pass a pole each second, the frequency is 4 Hz. If the wavelength is known, you can calculate the speed using the formula speed = frequency x wavelength.

What are the four units of speed?

The four units of speed are meters per second (m/s), kilometers per hour (km/h), miles per hour (mph), and feet per second (ft/s). Each unit represents a different measurement of speed based on distance traveled in a given time period.


What are the five main parts of sound and light waves?

Waves have a repeating series of crests and troughs. The crests are where a wave's amplitude is at its maximum. Between every two successive crests is a trough, where the wave's amplitude is at its minimum. The distance between two successive crests (or troughs) is the wavelength. The measure of how frequently new crests are formed is the frequency. The speed of a wave is the product of its wavelength and its frequency.


What are four characteristics of a wave that can change?

Four characteristics of a wave that can change are amplitude (height of the wave), frequency (number of wave cycles per unit time), wavelength (distance between wave crests), and speed of propagation.


As you sit on a dock you notice a wave crest pass You count another four wave crests in the next 12 seconds What is the frequency of these waves?

16 wave crests in 8 seconds is the same as 2 per second. 2 is the frequency - 2 Hertz, to be precise.16 wave crests in 8 seconds is the same as 2 per second. 2 is the frequency - 2 Hertz, to be precise.16 wave crests in 8 seconds is the same as 2 per second. 2 is the frequency - 2 Hertz, to be precise.16 wave crests in 8 seconds is the same as 2 per second. 2 is the frequency - 2 Hertz, to be precise.


What are four ways a 'wave' can be changed?

A wave can be changed by altering its amplitude (height of the wave), frequency (number of waves per unit time), wavelength (distance between wave crests), and speed (how fast the wave travels through a medium).

A wave on a lake passes by two docks that are forty meters apart If there is a crest at each dock and three crests between the two docks then what is the wavelength?

The distance between two consecutive crests is one wavelength. Since there are three crests between the two docks, this means there are four wavelengths in total between the two docks. Given that the two docks are forty meters apart, the wavelength of the wave passing between them is 40 meters divided by 4, which equals 10 meters.


Who has the second most masters tournament victories?

Tiger Woods and Arnold Palmer tied for second with four Masters victories each


2. A water wave vibrates up and down four times each second the distance between two successive crests is 5 meters and the height from the lowest part to the highest part of the wave is 2 meters?

The frequency of the wave is 4 Hz. The wavelength of the wave is 5 meters. The amplitude of the wave is 1 meter (half of the total height).
