Answer:

$E=2.04* 10^(-18)\ J$

Step-by-step explanation:

We need to find the energy for an electron to jump from n = 1 to n = 4.

The energy in transition from 1 state to another is given by :

$E=(-2.18* 10^(-18))/(n^2)\ J$

The difference in energy for n = 1 to n = 4 is:

$E=-2.18* 10^(-18)* ((1)/(4^2)-1)\\\\E=2.04* 10^(-18)\ J$

So, the required energy is equal to
$2.04* 10^(-18)\ J$ .
