Wavelength and sound

Thus, the speed of sound is proportional to the square root of the ratio of the bulk modulus of the medium to its density. Those physical properties and the speed of sound change with ambient conditions. For example, the speed of sound in gases depends on temperature. The speed of sound is also slightly sensitive, being subject to a second-order anharmonic effect, to the sound amplitude, which means there are non-linear propagation effects, such as the production of harmonics and mixed tones not present in the original sound see parametric array.

Get Access Wavelength and Sound Essay Sample Verification of the relationship between frequency of sound and its wavelength and the determination of the velocity and the speed of sound in different mediums was the main focus of this experiment.

A vernier microphone was used to note the time interval between wavelengths. The results obtained on the second and third experiment gathered a minimal compared error compared to the first experiment.

Introduction Sound is a longitudinal wave in a medium. Sound waves usually travel out in all directions from the source of sound, with an amplitude that depends on the direction and Wavelength and sound from the source.

A sound wave is a pressure disturbance that travels through a medium by means Wavelength and sound particle-to-particle interaction.

As one particle becomes disturbed, it exerts a force on the next adjacent particle, thus disturbing that particle from rest and transporting the energy through the medium.

Wavelength of Sound

Like any wave, the speed of a sound wave refers to how fast the disturbance is passed from particle to particle. While frequency refers to the number of vibrations that an individual particle makes per unit of time, speed refers to the distance that the disturbance travels per unit of time.

The speed of any wave depends upon the properties of the medium through which the wave is traveling. The phase of matter has a tremendous impact upon the elastic properties of the medium.

In general, solids have the strongest interactions between particles, followed by liquids and then gases. For this reason, longitudinal sound waves travel faster in solids than they do in liquids than they do in gases.

The objectives of this experiment is to verify the relationship between frequency of sound and its wavelength, to determine the speed of sound by means of a resonating air column and lastly, to determine the velocity if sound in a solid using a vibrating rod. A tuning fork was struck with a rubber mallet.

Wavelength and sound

The vibrating tuning fork was placed over the top of the glass tube. The water vessel was slowly lowered until the loudest sound was heard. The point where the sound was heard was marked. The vibration of the fork was made sure as the vessel was lowered.

The fork was struck again if the vibration stopped.


The distance between the point where the loudest sound was heard and the top of the glass tube was measured. This was recorded as L. The data gathered was converted to meters. The diameter of the resonance tube was measured and the wave length of the sound produced was computed.

Two more trials were made and the average wavelength was determined. The velocity of sound in air inside the glass tube was computed using the average wavelength and the frequency engraved in the tuning fork. The temperature was determined in degrees Celsius of air inside the glass tube. The thermometer was made sure that the water is not touched.

The speed of sound in air at that temperature was computed. The percent error was computed by comparing the speed of sound in air and the speed of sound in the resonating tube. The speed of air was used as the accepted value. The procedure was repeated for the other tuning forks. The data and observation was recorded.

Activity 2 The vernier microphone was connected to the channel 1 of the interface.Speed = Wavelength • Frequency The above equation is known as the wave equation. It states the mathematical relationship between the speed (v) of a wave and its wavelength (λ) and frequency (f).

Wavelength and Sound Essay Sample. Verification of the relationship between frequency of sound and its wavelength and the determination of the velocity and the speed of sound in different mediums was the main focus of this experiment.

This calculator will tell you the wavelength of any airborne audio frequency in inches, feet and metres, based on the speed of sound at sea level, and at 20 degrees Celsius or 72 degrees Farenheit. Note that with audio frequencies of 20Hz to 20,Hz the range of physical sizes of wavelengths is substantial (), and this causes no end of.

Sound Pressure - Sound Pressure is the force of sound on a surface area perpendicular to the direction of sound Speed of Sound in Air - Speed of sound in air at temperatures from to o C ( to o F) at standard atmospheric pressure - Imperial and SI Units.

Introduction to sound

The wavelength is changing with the changing of the temperature, because the speed of sound changes with the temperature. The air pressure and the acoustic . Wavelength is the distance between the crests of a wave. Many different things can move like waves, like strings, water, the air (sound waves), the ground (earthquakes), and light can be treated as a wave.
