Answer:
E = 0.09 × 10⁻¹⁷J
Explanation:
Given data:
wavelength of radiations = 200 nm (200× 10⁻⁹ m)
Energy absorbed = ?
Solution:
Formula:
E = hc/λ
h = 6.63× 10⁻³⁴ Js
c = 3 × 10⁸ m/s
Now we will put the values.
E = 6.63× 10⁻³⁴ Js × 3 × 10⁸ ms⁻¹ / 200× 10⁻⁹ m
E = 19.89 × 10⁻²⁶ J / 200× 10⁻⁹
E = 0.09 × 10⁻¹⁷J
