How many seconds is a 440 hertz sound wave?

Spread the love

For example, if f = 440 Hz, then T = 1/440 sec. = 2.27 ms.

What are the properties of waves answer key?

The basic properties of waves are amplitude, wavelength, frequency, and speed.

What is wave answer?

A wave is a disturbance in a medium that carries energy without a net movement of particles. It may take the form of elastic deformation, a variation of pressure, electric or magnetic intensity, electric potential, or temperature.

What is the wavelength of a sound wave with a frequency of 50 Hz the speed of sound is 342 m s?

Detailed Solution The correct answer is 600 m. Here given: frequency = 50 Hz, wavelength = 4 m.

What are 4 basic properties of waves?

All kinds of waves have the same fundamental properties of reflection, refraction, diffraction and interference, and all waves have a wavelength, frequency, speed and amplitude. All waves can be thought of as a disturbance that transfers energy.

What are the 7 properties of waves?

There are many properties that scientists use to describe waves. They include amplitude, frequency, period, wavelength, speed, and phase.

What is the unit of pitch?

The correct option is A hertz. The quantity on which the pitch of sound depends, is called frequency. Frequency is no. of oscillations made by each particle in the medium when sound propagates through it. Its S.I. unit is per second (s−1) or hertz (Hz).

Which sound wave has a higher pitch?

A higher frequency sound has a higher pitch, and a lower frequency sound has a lower pitch. In Figure 10.2 sound A has a higher pitch than sound B. For instance, the chirp of a bird would have a high pitch, but the roar of a lion would have a low pitch. The human ear can detect a wide range of frequencies.

Is frequency a loudness or pitch?

The pitch of a sound depends on the frequency while loudness of a sound depends on the amplitude of sound waves.

What are 4 types of waves?

  • Microwaves.
  • X-ray.
  • Radio waves.
  • Ultraviolet waves.

What are the 6 types of waves?

Usually, waves are around us, they can be sound waves, radio waves, water waves, sine waves, cosine waves, string waves, slinky waves, etc. These are created through disturbance. There are three types of waves.

What are two types of waves?

Waves come in two kinds, longitudinal and transverse. Transverse waves are like those on water, with the surface going up and down, and longitudinal waves are like of those of sound, consisting of alternating compressions and rarefactions in a medium.

What is the top of a wave called?

The highest part of the wave is called the crest. The lowest part is called the trough. The wave height is the overall vertical change in height between the crest and the trough and distance between two successive crests (or troughs) is the length of the wave or wavelength.

What type of wave is a sound wave?

Longitudinal waves A longitudinal wave is one where all the particles of the medium (such as gas, liquid or solid) vibrate in the same direction as the wave. Sound waves are longitudinal waves.

What is the amplitude of a wave?

amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path.

What are the 3 parts of a wave?

Wave Crest: The highest part of a wave. Wave Trough: The lowest part of a wave. Wave Height: The vertical distance between the wave trough and the wave crest.

What is the frequency of a wave?

Wave frequency is the number of waves that pass a fixed point in a given amount of time. The SI unit for wave frequency is the hertz (Hz), where 1 hertz equals 1 wave passing a fixed point in 1 second.

What is the speed of a wave?

Wave speed is the distance a wave travels in a given amount of time, such as the number of meters it travels per second. Wave speed is related to wavelength and wave frequency by the equation: Speed = Wavelength x Frequency.

What causes a wave to form?

Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.

What travels on a wave?

What travels on a wave? Energy travels on a wave. The waves carry the energy along without transporting matter from place to place.

Why is amplitude important?

It is the distance between the crest or trough and the mean position of the wave. Loudness is directly proportional to the amplitude of the sound. If the amplitude of a sound wave is large, then the loudness of the sound will be more. If the amplitude is small, then the sound will be feeble.

What is the SI unit for sound?

Since this energy can be measured, the most common SI unit of sound that is used is Decibel which is abbreviated as dB. This unit is basically used to express the ratio of some value of a physical property to another, mainly on a logarithmic scale. This is called as Decibel Scale or DB Scale.

What is the SI unit of frequency?

The number of periods or cycles per second is called frequency. The SI unit for frequency is the hertz (Hz).

What is the SI unit of wavelength?

The SI unit of wavelength is metre usually denoted as m. While measuring wavelength the multiples or fractions of a metre is also used.

What is the shortest wavelength?

Gamma rays have the shortest wavelength and the highest energy among the other waves in the electromagnetic spectrum. The wavelength of the gamma rays is less than 0.01 nanometers.
