Violet light has a wavelength of 4.10x10 to the power of -12m what is the frequency?

Sagot :

AL2006
Frequency of any wave = (the wave's speed) divided by (its wavelength)

Speed of light = about (3 x 10 to the 8) meters per second, in vacuum.

Frequency = (3 x 10 to the 8) / (4.1 x 10 to the -12) = 7.317 x 10 to the 19 Hz.

That's the same as 73,170,000,000 GHz.

Note: 
That's the answer for the information given in the question, but the information in
the question is incorrect by 5 orders of magnitude. The wavelength of violet light,
or anything in the visible range, is a few hundred 'nanometers' ... a few hundreds
of 10 to the -9 .  So the number in the question should be 4.10 x 10 to the -7,
not -12, and the frequency should be 731,700 GHz.
