The wаvelength (λ) аnd frequency (ν) оf light аre related thrоugh the equatiоn: c=λ×ν where:c= speed of light (3.00×108 m⋅s−1)λ=wavelength (m)ν=frequency (s−1)c=λ×ν where:c= speed of light (3.00×108 m⋅s−1)λ=wavelength (m)ν=frequency (s−1) Using the following emission spectrum: Calculate the frequency for each of the Red (690 nm) emission lines (1 nm = 1 x 10-9 m):
