Question

Find the energy in kJ for an x-ray photon with a frequency of 2.4 × 10^18 1/s.

Answer 1

Answer:

15912 × 10∧-19 KJ

Explanation:

Given data;

frequency of photon = 2.4 × 10^18 1/s.

Planck's constant = 6.63 × 10∧-34 j.s

Energy = ?

Formula:

E = h × ν

E =  6.63 × 10∧-34 j.s ×  2.4 × 10^18 1/s

E= 15.912 × 10∧-16 j

now we will convert the joule into kilo joule,

E = 15.912 × 10∧-16 j /1000 = 15.912 × 10∧-19 KJ
