What is the approximate frequency of a photon having an energy 5 x 10^-24 j?

key: h = 6.6 x 10 ^-34 j·s
how do i solve this ?

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)
