An electron makes a transition from a certain energy level E_k to the ground state E₀. If the frequency of emission is 8.0 x 10¹⁴Hz The energy emitted is

8.25 x 10^-19J

5.28 x 10^-19J

5.28 x 10¹⁹J

8.25 x 10¹⁹J

Correct answer is B

Atomic emission and absorption of energy is usually in packets referred to as photon or quantum of energy of magnitude E =hf, where f is the frequency and h is the plancks constant

Energy emitted = hf

= 6.6 x 10^-34 x 8.0 x 10^-14
= 5.28 x 10^-19J
