At 20 degrees Celsius or 68 degrees Fahrenheit the speed of sound c = 343 m/s. Wavelength lamda is 0.667 meters. Frequency f = c / lambda = 343 / 0.667 = 514.24 Hz.

500 Hz.
The speed of sound varies with temperature. At commonly experienced temperatures, it's about 343 meters/sec. Frequency = speed/wavelength = 343/0.686 = 500 Hz
Vacuums don't have frequencies.Electromagnetic waves moving through vacuums have frequencies and wavelengths.They also have speed. Regardless of their frequency and wavelength, their speed is always299,792,458 meters per second.The wavelength of an electromagnetic wave is [ (its speed) divided by (its frequency) ].If its frequency is 1.01 Hz, then its wavelength is 296,824,215.8 meters (about 184,438 miles).
Wave speed = (wavelengtth) x (frequency) = (10) x (110) = 1,100 meters per second
No change in frequency or wavelength.
The wavelength is the equal to the speed divided by the frequency. Hence: λ = v/f

The speed of a wave is equal to its wavelength times its frequency. Since you are using SI units, the answer will be in meters/second.

Wave speed = (wavelengtth) x (frequency) = (10) x (110) = 1,100 meters per second
IF a wave moving at a constant speed were to have it's wavelength doubled (Wavelength x 2), then the frequency of the wave would be half of what it originally was (Frequency / 2).
speed = distance over time = wavelength times frequency = 2 m times 10 hz = 20 m hz = 20 meters per second.
No change in frequency or wavelength.
Whatever the wavelength and frequency happen to be, their product is always equal to the speed.
The wavelength is the equal to the speed divided by the frequency. Hence: λ = v/f
The formula for a wave in this case is: speed = frequency x wavelength. Since Hz = 1/second, the answer will be in meter/second.
Any wave. Of you have a wave (light, water etc.), it will have a frequency and a wavelength. Multiply these and you get the speed at which the wave is moving.
