For any wave, the speed of the wave is the product of its frequency and of its wavelength.
0.4 m/
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.
speed of a wave = wavelength x frequency = 2.5m x 4Hz = 10m/s
The speed of the wave increases, the frequency remains constant and the wavelength increases. The angle of the wave also changes.
speed = frequency x wavelength
Divide the speed by the wavelength. (For any wave, the wavelength times the frequency is equal to the speed of the wave.)
Wave speed = wavelength x frequency 4.0 m/s = wavelength x 2.50 Hz 1.6 m = wavelength
Formula is velocity=frequency X wavelength so Wavelength = 5m
The relationship v = T * λ (speed = frequency * wavelength) is true for all waves. For anything with a constant speed, higher frequency means shorter wavelength.
The speed of sound in fresh water is approx 1,500 metres per second. So wavelength = speed/frequency = 2.94 metres.
Speed = frequency x wavelength So required speed = 0.5 * 1 = 0.5 m/s Problem is that the wavelength is not given, but I have taken as 1 m for granted. Hence the answer
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.
frequency
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 of a wave = wavelength x frequency = 2.5m x 4Hz = 10m/s
the product of wavelength and frequency is speed of propagation for a vacuum about 300,000 km/s, about the same in air, less for glass or water
