Question

The energy of a photon that has a frequency of 1.821 x 1016 5-1 is blank j?

Answer 1

1.207 ××10⁻¹⁷ J

Step-by-step 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
