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
