Answer:

f = 0.44 × 10⁹ Hz

Explanation:

Frequency of light = ?

Energy of photon = 2.92× 10⁻²⁵ j

Solution:

Formula:

E = h.f

E = energy of photon

h = planck's constant

f = frequency

f = E/h

f =2.92× 10⁻²⁵ j / 6.63 × 10⁻³⁴ Kg.m² /s

Kg.m²/s² = j

f =2.92 × 10⁻²⁵ Kg.m²/s² / 6.63 × 10⁻³⁴ Kg.m² /s

f = 0.44 × 10⁹ /s

s⁻¹ = Hz

f = 0.44 × 10⁹ Hz
