Respuesta :

The correct order is [tex]\lambda_{P} < \lambda_{Q} < \lambda_{R}[/tex]

since we know that

wavelength = hc/E

E is the energy

for P photon energy is high as it moved from 1 to 3

for Q it will next to P

Photon P shown moves an electron from energy level n = 1 to energy level n = 3. The electron jumps down to n = 2, emitting photon Q, and then jumps [tex]\lambda_{P} < \lambda_{Q} < \lambda_{R}[/tex]

down to n = 1, emitting photon R. The spacing between energy levels is drawn to scale.

there fore order of wavelength is [tex]\lambda_{P} < \lambda_{Q} < \lambda_{R}[/tex]

What is wavelength?

  • The distance between wave crests, or a person's overall attitude, is called a wavelength. The distance between two waves' crests serves as an illustration of wavelength.
  • When you and another person have the same overall mindset and can easily communicate, it is an example of being on the same wavelength.
  • The metre, commonly abbreviated as m, is the SI unit for wavelength. The multiples or fractions of a metre are also used to measure wavelength.
