The difference is the wavelength's of the two colors, Red is on the "right" end of the visible light spectrum and thus "bigger" wavelength about 640-700 nanometers while Green is more on the "left" side at around 500 nanometers.
AnswerSpeed of a wave = Wavelength x frequencyv = 0.5 x 500v = 250 m/sAnswerIf it is an electromagnetic wave, then the speed is that of light - 'c (in vacuum)'.
500 hertz
Note: The speed should be in units of cm/s rather than cm. The relation between the speed (v), frequency (f) and wavelength (λ) is: v = fλ. Therefore, f = v/λ = (500 cm/s) / (20 cm) = 25 Hz.
The equation needed is: V=fl Where V is the speed, f is the frequency and l is the wavelength. (the poxy thing won't let me enter a lamba sign) The key bit of information is "in a vacuum"; all waves in a vacuum travel at the same speed, 3x108ms-1. This is more commenly refered to as the speed of light, C. Therefore, f = V / l= C / l = 3x108 / 400x10-9 = 7.5x1014 Hz (Not in standard form that's: 750,000,000,000,000 Hz) (The '/' means divided by)

Wavelength = (speed) / (frequency) = (5,000) / (10) = 500 meters = 0.5 km.

500 hertz
The speed of sound varies with temperature. At commonly experienced temperatures, it's about 343 meters/sec. Frequency = speed/wavelength = 343/0.686 = 500 Hz
A frequency of 600000000MHz is better expressed as 600THz (TeraHertz). It has a wavelength of 500 nm (nanometres) which places it in the visible spectrum. This particular wavelength is somewhere in the green. Green light is from 495 to 570 nm.
Note: The speed should be in units of cm/s rather than cm. The relation between the speed (v), frequency (f) and wavelength (λ) is: v = fλ. Therefore, f = v/λ = (500 cm/s) / (20 cm) = 25 Hz.
500 nanometers is 0.000019685 inches.

Period = reciprocal of frequency = 1 / (500) = 0.002 second
