speed of a wave = wavelength x frequency = 2.5m x 4Hz = 10m/s
For any wave, the speed of the wave is the product of its frequency and of its wavelength.
Divide the speed by the wavelength. (For any wave, the wavelength times the frequency is equal to the speed of the wave.)
The speed of sound in fresh water is approx 1,500 metres per second. So wavelength = speed/frequency = 2.94 metres.
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.
340 meter per second
5 meters
Frequency = (speed) / (wavelength) =(18 miles per second) x (1,609.344 meters per mile) / (50 meters) = 579.4 Hz (rounded)This speed and frequency is awfully high for a water wave, but the math is the math.
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.
speed of a wave = wavelength x frequency = 0.4m x 2Hz = 0.8m/s
Just use the relationship: speed (of the wave) = frequency x wavelength. If the frequency is in hertz (cycles/second), and the wavelength in meters, then of course the speed will be in meters/second.
speed = frequency x wavelength
Wavelength = 0.4 m Wave speed = 0.4 . 2 = 0.8 m/s
The speed of any wave is the product of the frequency and the wavelength. Be sure to convert the nm to meters first (dividing by 1,000,000,000). - By the way, in a vacuum, all electromagnetic waves travel at the same speed, known as the speed of light - about 300 million meters/second. However, in other substances - such as air, or water - electromagnetic waves are slower.
I assume that a "solar signal" means light. Light moves at approximately 262 million meters per second in water, regardless of the frequency or wavelength of the light. Also, if light has a frequency of 1000 Hz, then it has a wavelength of 300 kilometers. The speed of light, c, is equal to the product of the frequency and the wavelength. In other words, c=f*w
Speed = (wavelength) x (frequency) = (480 Hz) x (3.1 m) = 1,488 meters/sec.(About 4.3 times the speed of sound in air !)
For any wave, the speed of the wave is the product of its frequency and of its wavelength.
Wavelength is found via WL = v/f. WL = 1430/286 = 5m
