which is higher in energy? Electromagnetic radiation with wavenumber 3000cm-1 or with wavelength 2 micro meter?

which is higher in energy? Electromagnetic radiation with wavenumber 3000cm^-1 or with wavelength 2 micro meter?

Solutions

Expert Solution

wavenumber = 3000cm^-1

wavelength = 2 micro meter

= 2 x 10^-6 m

= 2 x 10^-6 x 10^2 cm

= 2 x 10^-4 cm

wavenumber = 1 / wavelength

= 1 / 2 x 10^-4 cm

= 5000 cm-1

wavenumber = 5000 cm-1

energy = h C / wave length

= h C x wave number

energy is directly proportional to wave number . so

answer : higher energy is wavelength 2 micro meter
