Question

what is the kinetic energy acquired by hydrogen atom if it absorbs a light radiation of energy 1.08*10^-17

Answer 1

Answer:

joules.

Explanation:

Since we have ...................(1)

we know that

....................................(2)

and

so from (1) and (2) we get,

....................(3)

we know the de-brogile relation

..........................(4)

m = mass of electron

So,from (3) and (4) we get,

we know that the kinetic energy is given by

After putting values we get,

joules.
