Question

The wavelength (λ) of a spectral line of caesium is 460 nm. Calculate the frequency of the line.​

Answer 1

Answer:

we know, photons are moving with speed of light in vaccum. it means, when the wavelength of a spectral line of Cesium is 460nm. then, frequency of the line can be given by, speed of light in vaccum/wavelength of spectral line of Cesium. = 6.521 × 10¹⁴ Hz.
