Question

What is the frequency of a photon that has an energy of 7.2 × 10^-16 J ?

a) 4.8*10^-49 Hz

b) 9.2*10^-19 Hz

c) 2.4*10^-24 s-1

d) 2.8*10^-10 s-1

e) none of the above

Answer 1

none of the above options

Step-by-step explanation:

E = hf

E = 7.2 X 10^-16j

h = Planck constant = 6.6 X 10^-34

f = E/h

f = 7.2 X 10^-16/6.6 X 10^-34

f = 1.09 X 10^-50s-¹
