General Chemistry 1 - Wave model of light - 1
Electron emission from Molybdenum Mo requires light with a minimum frequency of 1.09 x 1015 Hz.
What is the wavelength of the light? In which region of the electromagnetic spectrum is the light emitted?
c = λν ⇒ λ = c/ν
λ = = 2.75 x 10-7 m = 275 nm
This is an ultraviolet light.
