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.

Two factors that describe the size of a wave are its amplitude and its wavelength. Amplitude is essentially the height of the wave (measured from the top of the crest to the midpoint). The wavelength is the distance from one crest to the next. The wavelength can be related to the velocity and the frequency of the wave, according to the equation: velocity = frequency * wavelength The velocity of the wave is a measure of how fast the crest is moving with time (meters per second). The frequency is a measure of how many crests pass a stationary point in a given time interval (cycles per second = Hz).

Frequency = (speed)/(wavelength) = 299,792,458/100 = 2,997,924.58 Hz.BTW . . . Photons always move at the speed of light.

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).

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

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

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).

Wave speed = (wavelengtth) x (frequency) = (10) x (110) = 1,100 meters per second

-===Answered by Cody p.===- 500 Hz.

Whatever the wavelength and frequency happen to be, their product is always equal to the speed.

No change in frequency or wavelength.
