Wavelength = speed/frequency = 350/640 = 54.7 centimeters (rounded)
Frequency = (speed) / (wavelength) = (51/102) = 0.5 Hz
1.5 meters.
"Meters" is not frequency. It's wavelength. If you know the wavelength in meters, divide 300 by it, and the result is the frequency in MHz. If you know the frequency in MHz, divide 300 by it, and the result is the wavelength in meters.
Frequency here would be.....,Frequency = velocity/wavelengthFrequency = 7(m/s)/10 meters= 0.7 s -1=======
5 meters
wavelength = speed / frequency Wavelength should be expressed in meters (m), speed in meters per second (m/s), and frequency in hertz (Hz). I assume by "ms" in the question you actually mean "m/s" since the former is "milliseconds" (a measure of time) and the later is "meters per second" (a measure of speed). 1000 / 50 = 20 meters
Wavelength = (speed) / (frequency) = (340) / (20,000) = 0.017 meter = 1.7 centimeter
speed = wavelength * frequency wavelength = 102 meters frequency = 250 Hz = 250 cycles/second 102 * 250 = 25500 meters/second
Wavelength = speed/frequency = 30/10 = 3 meters
The speed of a wave is equal to the product of its wavelength and its frequency. (If you want to have the speed in meters/second, convert the wavelength to meters first.)
The equation to use in this case is:speed (of the wave) = wavelength x frequency If the frequency is in hertz, and the wavelength is in meters, the speed will be in meters/second.
Answer: frequency = 272 Hz. Given the wave velocity (speed of sound) and wavelength, find the frequency of the wave. Velocity = 340.0 m/s, Wavelength = 1.25 m. Formulas: Velocity = wavelength * frequency. Frequency = velocity / wavelength. Calculation: Frequency = (340.0 m/s) / (1.25 m) = 272 Hz. (Where Hertz = cycles / second.)
