Answer:
f = 0.76 × 10¹⁰ Hz
Explanation:
Given data:
Energy of photon = 5 × 10⁻²⁴ J
Frequency = ?
Solution:
Formula:
E = h. f
f = frequency of photon
h = planck constant
E = energy of photon
Now we will put the values in formula
E = h. f
f = E / h
f = 5 × 10⁻²⁴ J / 6.6 × 10⁻³⁴ J.s
f = 0.76 × 10¹⁰ s⁻¹
or
f = 0.76 × 10¹⁰ Hz (s⁻¹ = Hz)
