Question

find the frequency of photon that will be emitted when an electron in Li is de-excited from n=3​

Answer 1

$\large\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\pink{R}}}}$

Speed of electromagnetic waves = c = 3 × 108 m/s Planck's constant = h = 6.63 × 10-34 Js. We want to calculate the frequency, wavelength and energy of the emitted photon, when the atom makes a transition from ni = 4 to nf = 2.

Answer 2

• Speed of electromagnetic waves = c = 3 × 108 m/s Planck's constant = h = 6.63 × 10-34 Js. We want to calculate the frequency, wavelength and energy of the emitted photon, when the atom makes a transition from ni = 4 to nf = 2.
