Vibrations of the hydrogen molecule can be H2modeled as a simple harmonic oscillator with the spring constant k=1.13x10^3N/m and mass m=1.67x10^-27 kg (a) What is the vibrational frequency of this molecule? (b) What are the energy and the wavelength of the emitted photon when the molecule makes transition between its third and second excited states?

Respuesta :

The vibrational frequency of this molecule is 8.23×10¹⁴.

The energy of the emitted photon is 0.542eV.

The wavelength is 2290 nm.

The vibrational angular frequency:

W= √k/m = 8.23×10¹⁴

B) Energy difference= hw

∆E = 0.542eV

C) Wavelength = 1240/0.542 = 2290 nm

What is Wavelength?

  • Wavelength is equally commensurable to frequence, which refers to the number of surge cycles per second. The advanced the frequency of the signal, the shorter the wavelength.  
  • A sound surge is a disturbance pattern caused by the movement of energy through a medium, similar as air, water, or any other liquid or solid, as it propagates down from the sound source.
  • A water surge is an illustration of a surge that involves a combination of longitudinal and transverse stir. An electromagnetic surge is created as a result of climate between an electric field and a glamorous field.
