Which of the following shows the Planck's quantum theory?

Correct answer: C. E = hv

  • A. E =hcv
  • B. E = c/v
  • C. E = hv
  • D. None of these options are correct

Explanation

In chemistry, Frequency is denoted by vSo, the Planck's quantum theory isE = hv where h is the Planck's constantIt can be rewritten asE = hc/λ since frequency(v) = c/λ where c is the speed and λ is the wavelength.

About Atomic Structure

Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
