Correct answer: D. Planck

  • A. Einstein
  • B. Maxwell
  • C. Newton
  • D. Planck

Explanation

The Planck constant (Planck's constant) tells us what would be the change in the energy of a photon when the frequency of its electromagnetic wave increases by 1 (In SI Units). It is named after the physicist Max Planck.In SI Units the Planck constant is exactly 6.626×10-34 J·s.

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.
