# What is the wavelength in feet of a 20 Hz sound wave traveling at 340 meters per second?

C=λv 340 m/s= 20 1/sec (λ) v= 17 m= ~56 ft

### A sound wave traveling at a speed of 340.0 meters per second has a wavelength of 1.25 what is the frequency?

Answer: frequency = 272 Hz. Given the wave velocity (speed of sound) and wavelength, find the frequency of the wave. Velocity = 340.0 m/s, Wavelength = 1.25 m. Formulas: Velocity = wavelength * frequency. Frequency = velocity / wavelength. Calculation: Frequency = (340.0 m/s) / (1.25 m) = 272 Hz. (Where Hertz = cycles / second.)

### What is the wavelength of a sound wave with a frequency of 250Hz?

Wavelength = (wave speed)/(frequency) . The speed of sound is influenced by the density of the material it's traveling through. If that's air, it depends on the temperature, humidity, pressure, altitude, suspended particulate matter, etc. Whatever the speed of the sound happens to be, the wavelength of a 250 Hz sound will be (speed, units per second)/(250) units. A typical speed of sound in sea-level air is around 340 meters per second. At that speed…

### What is the wavelength if the frequency of sound equals 880 Hz?

That would also depend on the speed. Note that sound can go at quite different speeds, depending on the medium and the temperature. Use the formula speed (of sound) = frequency x wavelength. Solving for wavelength: wavelength = speed / frequency. If the speed is in meters / second, and the frequency in Hertz, then the wavelength will be in meters.

### If you have a frequency of 670 what is it wavelength?

Depends on what the speed of the wave is. The wavelength is equal to the speed of the wave divided by its frequency. For light in a vaccum, for instance, the speed is c, or about 3.00 x 10e8 meters/second. If the frequency was in Hertz (cycles/second), then the wavelength would be 448,000 meters. So, this probably is a light frequency. If it were the sound at sea level, the speed is 340 meters/second, so…

### If Two waves are traveling in the same medium with a speed of 340ms What is the difference in frequency of the waves if the one has a wavelength fo 5m and the other has a wavelength of 0.2m?

For a wavelengt lambda in air with the speed of sound of c = 340 meters per second the frequency f: f = c / lambda. A wavelength of 5 meters equals a frequency of 68 Hz. A wavelength of 0.2 meters equals a frequency of 1700 Hz. There is a useful calculator for converting wavelength to frequency and vice versa.

### The speed of sound in water is 1430 meters per second What is the wavelength of a sound with a frequency of 286 Hz traveling through the water?

The formula for speed is velocity= wavelength x frequency If the speed of sound in water is 1430m/s you would replace that as the velocity. 1430= wavelength x frequency Frequency is 286 Hz, therefore you would replace that for the frequency in the equation. 1430= wavelength x 286 Now you would divide 1430 by 236, in order to get the wavelength alone. 1430/286= wavelength. So the wavelength is 5 m

### What is the wavelength of a sound wave in steel and an electromagnetic wave in vacuum having a frequency of 75 Hz?

-- The speed of sound in steel ranges generally between 3,000 - 6,000 meters per second, depending on the composition of the steel. A 75-Hz sound in steel would have a wavelength of 40 to 80 meters. -- The speed of electromagnetic radiation in vacuum is roughly 300,000,000 meters per second ... nominally 50,000 to 100,000 times the speed of sound in steel. A 75-Hz radio wave in vacuum has a wavelength of 4,000 kilometers.

### What is the wavelength of radiation at a frequency of 543.3Hz?

For a frequency f in air with the speed of sound of c = 343 meters per second the wavelength lambda = c / f. A frequency of 543.3 Hz meters equals a wavelength of 0.6313 meters. There is a useful calculator for converting wavelength to frequency and vice versa. Scroll down to related links and look at "Acoustic waves or sound waves in air".

### What is wavelength of sound?

In physics, wavelength is the distance between two successive identical parts of a wave It is commonly designated by the Greek letter lambda (λ). Sound waves are longitudinal waves; their wavelength can be measured as the distance between two successive compressions (higher pressure and density regions) or two successive compressions (lower pressure and density regions). Mathematically : wavelength of sound wave = speed of the wave / frequency where wavelength is measured in meters speed…

### What is the wavelength of 100 Hz?

What is the wave length of 100 Hz? Answer You mean a sound wave in air. At a temperature of 20 degrees Celsius or 68 degrees Fahrenheit there is the speed of sound c = 343 meters per second. For a tone of f = 100 Hz the wavelength is lambda = c / f = 343 / 100 = 3.43 meters. The equation for the relationship between wavelength and frequency is X = frequency…

### What is the relationship among frequency wavelength and wave speed?

Wave speed c = frequency f times wavelength lambda For a wave in air the speed of sound is c = 343 meters per second at 20 degrees Celsius. For a wave in vacuum the speed of light is c = 299 792 458 meters per second. frequency f = wave speed c divided by wavelength lambda. There is a useful calculator for converting wavelength to frequency and vice versa. Scroll down to related links…

### What is the wavelength of 42800 cps?

We use 42800 Hz now, and not cps. The wavelength can be calculated, when the medium is known. It may be air and then it is ultrasound. Wavelength lambda = Speed of sound c divided by frequency f. Speed of sound c is 343 meters per second at a temperature of 20 degrees Celsius or 68 degrees Fahrenheit.

### What is the period of a sound wave whose wave length is 20.0 m?

You solve this as follows: 1) Decide on a number for the speed of sound. Note that the speed of sound in air is quite different to the speed of sound in water, for example. Convert this speed to meters/second, if it isn't already in meters/second. 2) Divide the speed by the wavelength, to get the frequency. 3) The period is simply the reciprocal of the frequency.

### What is Middle c wavelength?

Middle C is C4 with a frequency f = 261,626 Hz. We asume the temperature of 20 degrees Celsius or 68 degrees Fahrenheit where the speed of sound is 343 meters per second. The wavelength in air lambda is the speed of sound c divided by frequency f. The wavelength lambda of middle C is 343 / 261,626 = 1.311 meters.

### What is the period of the wave having amplitude 1.25cm and wavelength 2cm?

The amplitude has nothing to do with the period of the wave, but you do have to know its speed. Period = (wavelength) / (speed) If you're talking about sound, then the speed is 343 meters per second. Period = (0.02) / (343) = 5.831 x 10-5 seconds = 0.00005831 second. If you're talking about electromagnetic waves, then the speed is 300,000,000 meters per second. Period = (0.02) / (300,000,000) = 6.67 x 10-11 second…
