Convert the cm to meters, to have compatible units. Then use the fact that the frequency times the wavelength is equal to the speed of the wave. In this case, you can divide the speed by the wavelength, to get the frequency.
It is 5 Hz.
Wave speed = (frequency) x (wavelength) = (80 per second) x (0.16 meter) = 12.8 meters/second
wave velocity = frequency in Hz x wavelength in meterSo frequency = 5 Hz and wavelength = distance between successive peaks = 20 cm = 20/100 mHence wave velocity = 5 * 20/100 = 1 m/s
Convert the wavelength to meters. Then simply multiply the frequency by the wavelength. The answer will be in meters/second.
Convert the cm to meters, to have compatible units. Then use the fact that the frequency times the wavelength is equal to the speed of the wave. In this case, you can divide the speed by the wavelength, to get the frequency.
Frequency = (speed)/(wavelength) = (12 cm/sec) / (3 cm) = 4/second = 4 Hz
It is 5 Hz.
Wave speed = (frequency) x (wavelength) = (80 per second) x (0.16 meter) = 12.8 meters/second
wave velocity = frequency in Hz x wavelength in meterSo frequency = 5 Hz and wavelength = distance between successive peaks = 20 cm = 20/100 mHence wave velocity = 5 * 20/100 = 1 m/s
Speed = (frequency) x (wavelength) = (5) x (3 cm) = 15 cm/sec
Convert the wavelength to meters. Then simply multiply the frequency by the wavelength. The answer will be in meters/second.
5*3 = 15 cm per second.
The frequency of a wave is not directly related to the wave length. A low frequency wave or a high frequency wave may be either long-wave or short-wave.
15 cm per second
velocity of a wave equals wave frequency times wave length.
speed (of the wave) = frequency x wavelengthspeed (of the wave) = frequency x wavelengthspeed (of the wave) = frequency x wavelengthspeed (of the wave) = frequency x wavelength
