Question

The wavelength of transmission is 9.7mm. What is the energy of this transition

Answer 1

Answer:

E = 2.05×10⁻²³ J

Explanation:

Given data:

Wavelength of transmission = 9.7 mm (9.7/1000 = 0.0097 m)

Energy of transition = ?

Solution:

9.7 mm (9.7/1000 = 0.0097 m)

9.7×10⁻³ m

Formula:

E = hc/λ

By putting values,

E = 6.63 ×10⁻³⁴ Js × 3×10⁸ m/s / 9.7×10⁻³ m

E = 19.89×10⁻²⁶ J.m / 9.7×10⁻³ m

E = 2.05×10⁻²³ J
