Physics Homework. Determining light frequencys HELP QUICK?

Question

Ok, i have a physics test tomorow, and for some odd reason i dont have a note about determining light frequencies.

Here is the study question we are issued:

What is the frequency of light that has a wavelength of 480 nm

Answer 1

If light has a wavelength L meters and travels C meters/second... it will travel F wavelengths in a second.

So: F=C/L (F-Cycles per second, or Hertz)

(Actually, in physics it's typically small F, small C, and LAMDA for wavelength, which is the upside-down "y" thingy.

So:
c= 299,792,458 metres per second - let's say 3.00x10^8m/s
1 nanometer = 10^-9 m.

f=c/L=3.00x10^8/(480x10^-9) (convert to meters).
Got a caculator?

Answer 2

The sunlight is rotating from left to ideal. is sensible ideal? I mean because easy can't circulate any quicker than the cost of sunshine. once you progression some thing, shall we are saying a easy bulb, in a motor vehicle, the frequency ameliorations as a replace of the cost to account for the greater power it could've gained if it have been a ball as a replace or some thing. A ball btw could circulate the cost of the motor vehicle + velocity at which the ball became into released. So confident, in case you quickly sufficient you will discover a pink easy as though it became into green. Its formally referred to as Doppler consequence. Ha actual contributers, i don't comprehend a word you suggested XD
