Answer:
Energy Of Photon = hc/∝
∝ = 20*10^-26/5.862*10^-16
3.411*10^-10
Answer:
3.41 × 10⁻¹⁰ joules
Explanation:
E = nhυ = nhc / λ
here
E - Energy
υ - frequency of light
n - no of photons = 1
h - Planck's constant = 6.626 × 10⁻³⁴
c - speed of light = 3 × 10⁸
λ - wavelength of light = 5.862 x 10⁻¹⁶
E = nhc / λ
= 1 × 6.626 × 10⁻³⁴ × 3 × 10⁸ / 5.862 x 10⁻¹⁶
= 20 × 10⁻²⁶ / 5.862 x 10⁻¹⁶
= 3.41 × 10⁻¹⁰ joules
