Speed = (wavelength) x (frequency) = 0.5 x 20 = 10m/sec
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.
Wave speed = (frequency) x (wavelength) = (50) x (20) = 1,000 meters.
340 m/s
For light they would be gamma rays, or waves with a frequency greater than 1 * 10^20 (10000000000000000000) Hz. And really, as a general rule, the higher the frequency the shorter the wavelength. If you want to calculate the frequency or wavelength you take the speed of light (~3.00*10^8 m/s) and divide it by either the frequency or wavelength, and your answer will be the wavelength (if you used frequency) or the frequency (if you used wavelength).
Use the fact that the frequency, multiplied by the wavelength, is equal to the speed of a wave. In a vacuum, light will move at 300 million meters/second; just divide this speed by the frequency.
Wavelength = (speed) divided by (frequency) = 10/0.5 = 20
Frequency = (speed)/(wavelength) = 10/20 = 1/2
Frequency = (speed)/(wavelength) = 20/2 = 10 Hz

With a speed of 331 m/s and a frequency of 20 Hz the wavelength is (331 m/s)/(20 Hz)=16,55 m .
Frequency = Velocity / Wavelength = 100 m/s / 20 m = 5 s-1 or 5 Hz.
(frequency) multiplied by (wavelength) = (wave speed)
