alright if u use the formula c = greek letter for wave length * v
c stands for 3.00 x 10^8 m/s and you use the number 7.04 for wavelength how would u find the frequency

I think you've got your equations down wrong.
Wavelength should have units of length, it shouldn't be a scalar. We always used lambda for wavelength, so that first equation should be
c = (lambda)*freq.
for a light wave. Check your book again.
In any case, frequency for a wave is velocity over wavelength, so that's:
freq. = v / (lambda) [units are 1/s or "Hertz" / Htz / Hz]
If we're dealing with light, obviously we only need the second equation because light moves at a constant speed, c.

the only subject i can think of of superb now that relates the temperature to wavelength is Wien's Displacement regulation: Wavelength * T = 2.8*10(-3)m-ok Frequency = c / wavelength c is the cost of sunshine. while you're having issues on a attempt look into the gadgets. you are able to sparkling up a super sort of issues in case you cancel out the splendid gadgets to get the respond you prefer.

frequency will be speed divided by wavelength.. Play around with the formulae!

3.00 x 10^8 m/s--c
c = λ × f
U HAVE C AND λ
SO BASICALLY c/ f =λ
3.00 x 10^8m/s / 7.04nm
BUT CHANGE YOU 7.04NM TO METRES IF IT IS IN METRE LEAVE IT OTHERWISE DO AS FOLLOWS:
7.05nmX10^-9m/1nm=???
THEN JUST APPLY IT c/ f =λ
and you find your frequency!
