Does a waves frequency equal the frequency of the vibrating source producing it?

Does a waves frequency equal the frequency of the vibrating source producing it?

Any periodic motion has a frequency, which is the number of complete cycles in a given time. Frequency is measured in cycles per second, or hertz (Hz). A wave’s frequency equals the frequency of the vibrating source producing the wave.

How is the wavelength related to frequency for waves moving at constant speed?

Explanation: There is an inverse relationship between frequency and wavelength. If the speed is held constant, as frequency increases, the wavelength must decrease.

What aspect of sound is the energy of vibration of the source related to?

Sound energy, or energy associated with the vibrations created by a vibrating source, requires a medium to travel, which makes sound energy a mechanical wave.

What happens when the frequency of a vibrating source that creates a wave doubles?

Wave speed may equal frequency*wavelength. Yet doubling the frequency only halves the wavelength; wave speed remains the same. To change the wave speed, the medium would have to be changed.

What happens as the frequency of a wave increases?

From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer. There are two basic types of waves: mechanical and electromagnetic.

What two factors are used to determine the frequency of waves?

The number of waves that pass a fixed point in a given amount of time is wave frequency. Wave frequency can be measured by counting the number of crests (high points) of waves that pass the fixed point in 1 second or some other time period. The higher the number is, the greater the frequency of the waves.

What is relationship between frequency and wavelength?

The shorter the wavelength, the higher the frequency. Hence, frequency and wavelength are inversely proportional to each other. Because all light waves move at the same speed in a vacuum, the number of wave crests passing at a given spot in one second is determined by the wavelength.

Which type of wave can travel in a vacuum?

Electromagnetic waves
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

Why do sound waves do not travel in a vacuum?

Sound waves are travelling vibrations of particles in media such as air, water or metal. So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate.

Do humans have a resonant frequency?

Human bodies are often exposed to vertical vibrations when they are in the workplace or on vehicles. By testing the response of the human body on a vibrating platform, many researchers found the human whole-body fundamental resonant frequency to be around 5 Hz.

What happens to sound if the frequency of the vibrations increases?

A low-pitched sound is a sound whose pressure fluctuations occur with a low period. If an object vibrates at a relatively high frequency, then the pitch of the sound will be low. Doubling the frequency of a sound wave will halve the wavelength but not alter the speed of the wave.

What difference will it give if frequency increase?

The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.
