Question

A photon has a wavelength of 6.2 meters. Calculate the energy of the photon in joules. (Planck's constant is 6.626 × 10-34 joule seconds, the speed of light is 2.998 × 108 m/s) 3.564 × 10-43 joules 3.204 × 10-26 joules 41.08 × 10-34 joules 13.702 × 10-42 joules
Answer B

Answer 1

plato ppl the answer is b

Answer 2

Energy of photon = hc/λ = $\frac{6.626*10 ^{-34}*2.998*10 ^{8}}{6.2} = 3.204*10 ^{-26}$ J. Hope this helps you!
