need to know the speed of the wave
at the speed of light 300,000,000 m/s
300,000,000 / 20 = 15,000,000 metres
at the speed of sound 333 m/s
333 / 20 = 16.67 metres
Wavelength = (speed) divided by (frequency) = 10/0.5 = 20
Frequency = (speed)/(wavelength) = 20/2 = 10 Hz
speed = distance over time = wavelength times frequency = 2 m times 10 hz = 20 m hz = 20 meters per second.
Divide the speed by the frequency
Freq = Speed/Wavelength = 37.5/25 Hz = 1.5 Hz
The longest wavelength that a human can hear corresponds to a frequency of about 20 Hz, which is typically the lower limit of human hearing. Wavelength and frequency are inversely proportional; as frequency decreases, wavelength increases.
With a speed of 331 m/s and a frequency of 20 Hz the wavelength is (331 m/s)/(20 Hz)=16,55 m .
The wavelength for a sound wave with a frequency of 20 Hz is approximately 17 meters. This can be calculated using the formula: wavelength = speed of sound / frequency.
The speed of a wave is calculated by multiplying its wavelength by its frequency. Therefore, the speed of the wave with a 0.2 Hz wavelength and 100 meters frequency would be 20 meters per second (0.2 Hz * 100 meters = 20 m/s).
Wavelength = (speed) divided by (frequency) = 10/0.5 = 20
Frequency = (speed)/(wavelength) = 20/2 = 10 Hz
40 Hz
velocity = frequency × wavelength frequency = velocity / wavelength f= 100 /20 f= 5 Hz
o.o1 nanometers < wavelength <0.06 nanometers, which corresponds to energies of 20 to 100 keV
speed = distance over time = wavelength times frequency = 2 m times 10 hz = 20 m hz = 20 meters per second.
Speed = (wavelength) x (frequency) = 0.5 x 20 = 10m/sec
To find the speed of the wave, you can use the formula: speed = frequency x wavelength. Given the frequency is 0.2 Hz and wavelength is 100 meters, you can calculate the speed of the wave as 0.2 Hz x 100 meters = 20 meters per second.
