Infared light has a lower frequency than visible light.  What is the frequency of IR light that has a wavelength of 680 nm?


Expert Answer

Step 1


Wavelength of IR light, λ = 680 nm

Velocity of light, c = 3 X 108 m/s

Step 2

Frequency of infrared light ...

V =
cis the speed of light
2is the wavelength
vis the frequency
plug in the values
V =
680 x109
v = 4.41x 1014Hz
