The answer will depend on what type of signal it is: acoustic, electromagnetic and in what medium the signal is propagated.
The answer is in the question! 5 Hz Also, a wavelength cannot be 5 cycles - wrong units.
I've got no idea what a "5 cycle wavelength" is. However, I would just apply this formula: v = fλ, where v is the velocity (speed in m/s) of the wave, f is the frequency (in hertz), and λ is the wavelength (in m).
Wavelength = (speed)/(frequency)Frequency = 1/periodso wavelength = (speed) x (period)Speed = (20 meter/min) x (1 min/60 sec) = 1/3 meter/secWavelength = (speed) x (period) = (1/3 meter/sec) x (30 sec) = 10 metersThe correct choice is a .
speed of sound in air 334 m/s 334/0.25 = 1336 Hz
The length of a rectangle whose area is 72 square meters and whose width is 6 meters, would be 12. Note that 12 x 6 = 72.
12.5 terahertz. If your wavelength is in meters.
Divide the speed of light (in meters/second) by the wavelength (in meters). The answer is in Hz (1/second). Divide that answer by a million to get MHz.
Speed (of a wave) = frequency x wavelengthTherefore, you have to: * Convert the wavelength to meters. * Divide the speed of light - which is 300 million meters/second - by this wavelength. The answer will be in Hz.

Mix it with a local oscillator whose frequency is (the IF frequency) away from the frequency of the FM signal you're interested in.
Divide the speed of sound by the wavelength, to get the frequency. The period is the reciprocal of the frequency. The speed of sound in air is about 343 meters/second, but it depends on temperature. The speed of sound in other materials is quite different from the speed of sound in air.
Twice the energy means twice the frequency, and therefore half the wavelength.
A low pass signal whose bandwidth is much smaller than its center frequency, such as an AM signal. It is a a signal with its spectrum concentrated around zero frequency.
modulating signal is the message to be carried by the carrier signal.

It depends on the speed of sound considered for the situation, as sound can travel at different speeds depending on the temperature of the air, its density, composition, etc. For all types of waves (sound waves included), the wavelength is equal to the speed of the wave, divided by its frequency. So, if you consider the speed of sound to be 330 m/s, the wavelength in question would be equal to 330/50, or 6.6 meters. If you consider the speed to be 340 m/s, the wavelength would be 6.8 meters.
