Answer:
1.207 ××10⁻¹⁷ J
Explanation:
Step 1: Given and data
- Frequency of the photon (ν): 1.821 × 10¹⁶ s⁻¹
- Planck's constant (h): 6.626 × 10⁻³⁴ J.s
Step 2: Calculate the energy (E) of the photon
We will use the Planck-Einstein's relation.
E = h × ν
E = (6.626 × 10⁻³⁴ J.s) × ( 1.821 × 10¹⁶ s⁻¹) = 1.207 ××10⁻¹⁷ J
