Planck's equation is:
Correct answer: C. E=hν
- A. E=mc2
- B. mvr=nh/2π
- C. E=hν
- D. λ=h/mv
Explanation
Planck's equation describes the relationship between the energy of a photon and its frequency. The most common form of Planck's equation is:E = hνWhere:E is the energy of the photon.h is Planck's constant (approximately 6.626 x 10⁻³⁴ joule-seconds).ν (nu) is the frequency of the radiation.It's also common to see it expressed in terms of wavelength:E = hc/λWhere:c is the speed of light.λ (lambda) is the wavelength of the radiation.

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.
