Question

Calculate the energy of radiation whose wavelength is 700nm.​

Answer 1

3 × 10⁻¹⁹ is the energy produced

Step - by - step Explanation: Since we know this important formula of energy of photon

E = hc/λ

• λ = 700 nm or 700 × 10⁻⁹
• c = 3 × 10⁸
• h = 6.63 × 10⁻³⁴

→ E = 6.63 × 10⁻³⁴ × 3 × 10⁸ × 1/(700 × 10⁻⁹)

→ E = 0.03 × 10⁻¹⁷

→ E = 3 × 10⁻¹⁹

It was Max Planck, a German Physicist who told that energy should rather behave as a particle than a wave to carry out photoelectric effect where the energy of photon released is hv where h stands for Planck's constant & v (niu) stands for frequency.
