Greater the wavelength associated with the photon
Correct answer: B. Smaller is its energy
- A. Greater is its energy
- B. Smaller is its energy
- C. Its energy will be variable
- D. Its energy will remain constant
Explanation
The energy of a photon is given by Planck's equation asE=hc/ λSince energy is inversely proportional to the wavelength of a photon so a photon of greater wavelength will have smaller energy, the amount of energy for a single photon is discrete for a fixed wavelength, in the sense that you will find only integer multiples of that energy hc/λ at that given wavelength, and the photon can only ever deliver energy hc/λ, not some fraction.

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.
