An electromaghetic radiation has an energy 14 . 4 keV . To which region of the electromagnetic spectrum it belongs

Step-by-step solution

Recall the formula of energy, E = h c λ = 14 . 4 × 1000 × 1 . 6 × 10 - 19   J ⇒ h c λ = 6 . 6 × 10 - 34 × 3 × 10 8 λ = 14 . 4 × 1000 × 1 . 6 × 10 - 19   J ⇒ λ = 6 . 6 × 10 - 34 × 3 × 10 8 14 . 4 × 1000 × 1 . 6 × 10 - 19   J = 0 . 859 × 10 - 10   m ⇒ λ ≈ 1   A ∘   X-rays
