Answer:
E = 2.80×10⁻¹⁶ j
E = 5.37×10⁻¹⁷j
Step-by-step explanation:
Given data:
Frequency of photon = 4.23 ×10¹⁷ Hz
Energy of photon = ?
Solution:
Formula:
E = h× f
E = 6.63×10⁻³⁴ js ×4.23 ×10¹⁷ Hz
Hz = s⁻¹
E = 28.0×10⁻¹⁷ j
E = 2.80×10⁻¹⁶ j
2)
Given data:
Frequency of photon = 8.10×10¹⁶ Hz
Energy of photon = ?
Solution:
E = h× f
E = 6.63×10⁻³⁴ js × 8.10×10¹⁶ Hz
Hz = s⁻¹
E = 53.7×10⁻¹⁸j
E = 5.37×10⁻¹⁷j
