Question

Calculate (a) wavenumber and (b) frequency of yellow radiation having wavelength 5800 Å.

Yellow light emitted from a sodium lamp has a wavelength (λ) of 580 nm. Calculate the frequency (ν) and wavenumber (v̄) of the yellow light.

Calculate the wavelength, frequency and wavenumber of a light wave whose period is 2.0 × 10–10 s.

In Rutherford's experiment, generally the thin foil of heavy atoms, like gold, platinum etc. have been used to be bombarded by the α-particles. If the thin foil of light atoms like aluminium etc. is used, what difference would be observed from the above results ?
