Answer:

E = 8.84×10⁻¹⁷ J

Explanation:

Given data:

Wavelength of wave = 2.25 nm (2.25×10⁻⁹ m)

Energy of wave = ?

Solution:

Formula:

E = hc/λ

c = 3×10⁸m/s

h =6.63 ×10⁻³⁴ Js

now we will put the values,

E = 6.63 ×10⁻³⁴ Js ×  3×10⁸m/s / 2.25×10⁻⁹ m

E = 19.89×10⁻²⁶ Jm / 2.25×10⁻⁹ m

E = 8.84×10⁻¹⁷ J
