Answer:
E = 23.54 ×10⁻¹⁷ j
Explanation:
Given data:
Frequency = 3.55 ×10¹⁷ Hz
Energy of photon = ?
Solution:
Formula:
E = h. f
E = energy of photon
h = plancks constant (6.63×10⁻³⁴ Kg.m²/s)
f = frequency of photon
Now we will put the values in formula.
E = 6.63×10⁻³⁴ Kg.m²/s × 3.55 ×10¹⁷ Hz
Hz = s⁻¹
E = 6.63×10⁻³⁴ Kg.m²/s × 3.55 ×10¹⁷ s⁻¹
E = 23.54 ×10⁻¹⁷Kg .m²/ s²
Kg .m²/ s² = j
E = 23.54 ×10⁻¹⁷ j
