Answer 1

Answer:

λ = 4.59 ×10⁻³ nm

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
