All light travels in the speed of light in vacuum, that is 300,000 km/sec. The relevant formula is C = f*lambda, where C is the speed of light, f is the frequency and lambda the wavelength. Therfore, f = C/lambda. Here lambda = 632.8nm, so f = 4.741E14 or 474 terahertz.
The color of this light, incidentally, is red. Please see the links. They are beautiful, anyway.

The wavelength is 671 nm.
The wavelength is 671 nm.

according to the wave theory of light,we have the relation that wavelength is inversely proportional to the frequency,therefore the electromagnetic wave with the lower wavelength will have higher frequency..
The wavelength is 671 nm.
The wavelength is 671 nm.
Just divide the speed of light (in meters/second) by the frequency (in hertz) - that will give you the wavelength (in meters). You can then convert that to nm.
