Answer:
λ = 4.59 ×10⁻³ nm
Step-by-step explanation:
Given data:
Energy of light = 4.33 ×10⁻¹⁴ J
Wavelength of light = ?
h = 6.626×10⁻³⁴ js
c = 3×10⁸ m/s
Solution:
Formula:
E = hc/λ
4.33 ×10⁻¹⁴ J = 6.626×10⁻³⁴ Js× 3×10⁸ m/s / λ
λ = 6.626×10⁻³⁴ Js× 3×10⁸ m/s / 4.33 ×10⁻¹⁴ J
λ = 19.878 ×10⁻²⁶ Jm / 4.33 ×10⁻¹⁴ J
λ = 4.59 ×10⁻¹² m
λ = 4.59 ×10⁻³ nm
