Wavelength and sound

This produces aliasing because the same vibration can be considered to have a variety of different wavelengths, as shown in the figure. Frequency which is the number of times a sound wave occurs. Sound pressure which is the local pressure derived from atmospheric pressure of the sound waves.

Wavelength is dependent upon several features such as; crests or peaks, troughs or valleys, and zero crossings to determine its strength.

The theoretical speed of sound and the percent error was also computed. Please spread the word. Activity 2 The vernier microphone was connected to the channel 1 of the interface.

Earthquakes have very low frequencies; ultrasound waves have very high frequencies. In non-vacuum media The speed of light in most media is lower than in vacuum, which means that the same frequency will correspond to a shorter wavelength in the medium than in vacuum.

Difference Between Wavelength and Frequency

Introduction Sound is a longitudinal wave in a medium. The speed of any wave depends upon the properties of the medium through which the wave is traveling. It is measured in hertz and is the vibration that is caused by the contact between sound waves and peaks or troughs.

The range of wavelengths sufficient to provide a description of all possible waves in a crystalline medium corresponds to the wave vectors confined to the Brillouin zone. The microphone was positioned near the open end of a closed tube. This is called frequency. The wavelength in the medium is where n is the refractive index of the medium.

In general, solids have the strongest interactions between particles, followed by liquids and then gases. It is mathematically equivalent to the aliasing of a signal that is sampled at discrete intervals.

The fork was struck again if the vibration stopped. The speed of sound in air at that temperature was computed. Relationship with frequency The wavelength of a wave or wavelike phenomenon is related to the frequency by the formula: The percent error was computed with the same accepted value used in activity 1.


The data gathered was converted to meters. Question-specific help is provided for each of the 12 situations.Wavelength is an important consideration in engineering fields that work with sound waves (or radio waves) traveling a distance through a physical material like air. Examples would be acoustic treatments, speaker building.

Sound waves travel about one million times more slowly than light waves but their frequency and wavelength formulas are somewhat similar to light wave formulas. the Greek letter lambda λ is the symbol for wavelength.

Wavelength sound wave air acoustic sound waves calculation temperature frequency wave no air pressure speed of sound - Eberhard Sengpiel sengpielaudio. Practicing calculating the wavelength and frequency of sound waves created in open and closed tubes. Feb 13,  · Wavelength vs Frequency Sound is the vibration of pressure in the form of mechanical waves or sound waves which are transmitted through any form of matter whether solid, liquid, or gas.

It has several characteristics and properties such as the following: Amplitude which is the measure of change in the oscillation of.
