In the hydrogen atom, the energy spacing between the is 4.07 x 101 j (joules). when an is the frequency of the photons emitted? electron falls from the fourth to the second orbital, what from the a. 3.04 x 10 hz (or cycles per second) b. 608 x 1014 ã c. 3.04 x 1015 hz d. 4.00 x 10'"hz e. 4.00 x 10 hz

The frequency of the photon is .

Explanation:

Given that,

Energy

We need to calculate the energy

Using relation of energy

Where, =  energy spacing

Put the value of h into the formula

Hence, The frequency of the photon is .

the rearrangement of particles in a physical change. hope this
