What is the frequency of radiation whose wavelength is 16.40 脜



What is the wavelength of radiation that has a frequency of 2.4 1012 s-1?What is the frequency of radiation whose wavelength is 16.40 脜?
Planck's Law

位 = c/v

Where: 位 = wavelength c = speed of light and v = frequency

Note:
The speed of light = 299,792,458 m/s
1 脜 = 100 x 10^-12 m
Therefore 16.40 脜 = 1.64 x 10^-9 m

Now we can calculate the frequency.

v = c/位 = (299,792,458 m/s)/(1.64 x 10^-9 m)
v = 1.828 x 10^17 (1/s)

For the second question use the same equation

位 = c/v = (299,792,458 m/s)/(2.4 x 10^12 s-1)
位 = 1.249 x 10^-4 m

Hope this help!!!!

Note: If you answer the question as the person said above you will get a frequency with units of energy. It is E = h*v not 位 = hvWhat is the frequency of radiation whose wavelength is 16.40 脜?
wavelength = h * frequency (h is planks constant = 6.626 ^-34)

convert 16.40 A to m = 1.64^-9 m

so frequence is 1.64^-9/6.626^-34

=2.486^24 s-1



The other one is solved simlarly. The answer is 1.6^-21
