What is the velocity if the wave length is 0.1 and the frequency 3000 ?
1 Answer
It all depends on what units of measurement you apply.
Explanation:
Set the wave length units of measurement as Metres
Set the frequency as Hertz (cycles per second - Hz)
Set the length of time measured for as 1 second
Distance for 1 second
So for your questions solution we have:

From which I obtained:
The speed of light is defined exactly as 299,792,458 m/s. A photon of red-orange light from a HeNe laser has a wavelength of 632.8 nm. Using the equation gives a frequency of
Note that
A nanometre is a unit of spatial measurement that is 10 to the -9th meter, or one billionth of a meter
