Webster’s dictionary defines a wave as: a disturbance or variation that transfers energy progressively from point to point in a medium and that may take the form of an elastic deformation or of a variation of pressure, electric or magnetic intensity, electric potential, or temperature.

Frequency is the number of occurrences of a repeating event per unit of time. Frequency is measured in hertz (Hz) which is equal to one event per second. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency.

The frequency, represented by the Greek letter nu (ν), is the number of waves that pass a certain point in a specified amount of time. Typically, frequency is measured in units of cycles per second or waves per second. One wave per second is also called a Hertz (Hz) and in SI units is a reciprocal second (s−1).

The wavelength (or alternatively wavenumber or wave vector) is a characterization of the wave in space, that is functionally related to its frequency, as constrained by the physics of the system. Sinusoids are the simplest traveling wave solutions, and more complex solutions can be built up by superposition.

Definition: Wavelength can be defined as the distance between two successive crests or troughs of a wave. It is measured in the direction of the wave. This means the longer the wavelength, lower the frequency.

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.

Wavelength: The distance between 2 consecutive crest or troughs is called Wavelength. It is represented by the symbol λ(lamda).

Sonar stands for Sound Navigation And Ranging. It is a device which is used to find distance, direction and speed of underwater objects like, water hills, valleys, icebergs, submarines, sunken ships etc.

If a sound is made in a big hall,the sound waves are reflected repeatedly from walls,ceiling and floor of hall,and produces many echoes. The persistence of sound in big hall due to repeated reflections from walls,ceiling,floor of the hall is called reverberation.

λ = v/f. The Wavelength is expressed in m, velocity is expressed in m/s, frequency is expressed in Hz.

Apply the de Broglie wave equation λ=hmv λ = h m v to solve for the wavelength of the moving electron.

Solution: Given, the wavelength of the photon particle = 500 nm. In order to calculate the frequency of the photon particle, we use the formula given above. The frequency of the wave is equal to 6×10-4 Hz.

Pitch is the rise and fall of our voice when we speak. It is the characteristic of sound by which we can distinguish the sounds of the same loudness.

Children will often mix up pitch and loudness believing that a higher pitched sound is a louder one. Higher pitched sounds produce waves which are closer together than for lower pitched sounds.

Pitch is a measure of how high or low something sounds and is related to the speed of the vibrations that produce the sound. Volume is a measure of how loud or soft something sounds and is related to the strength of the vibrations.

Difference between Pitch and Loudness The pitch of a sound is our ear’s response to the frequency of sound. Whereas loudness depends on the energy of the wave. The pitch of a sound depends on the frequency while loudness of a sound depends on the amplitude of sound waves.

For a person with normal hearing, when it comes to pitch the human hearing range starts low at about 20 Hz. That’s about the same as the lowest pedal on a pipe organ. On the other side of the human hearing range, the highest possible frequency heard without discomfort is 20,000Hz.

The answer to this question is clearly no. You might suspect, that the higher the frequency, the louder we perceive a noise, but frequency does not tell us how loud a sound is. Intensity or loudness is the amount of energy of a vibration and is measured in decibels (dB). If a sound is loud, it has a high intensity.

Answer. Answer: Loudness depends on the hearing range of the person. The loudness also depends on the person’s hearing ability.
