Expert Answer

Step 1

Given that,

Energy in n = 1 state is E1 = -2.18 × 10-18 J

Energy in n = 3 state is E3 = -2.42 × 10-19 J

The amount of energy absorbed E = 1.94 × 10-18 J

This absorbed energy is the energy difference between energy E3 and energy E1 i.e;

E3 – E1 = 1.94 × 10-18 J

Step 2

The wavelength of the photon can be calculated by using the formula as follows:

Here,

E is the energy absorbed = 1.94 × 10-18 J

h is the plank’s constant = 6....
