Question
At one time the meter was defined as 1650763.73 wavelength of the orange light emitted by a light source containing Kr86 atoms. What is the corresponding photon energy of this radiation?
Answer: A
💡 Solution & Explanation
λ = 1/1650763.73 m = 6.058 × 10^-7 m. E = hc/λ = (6.626 × 10^-34 × 3 × 10^8) / (6.058 × 10^-7) = 3.28 × 10^-19 J.
