Calculate the energy of light with wavelength of 400 nm in MeV (106 eV)
Added by Jennifer A.
Step 1
626 × 10^(-34) Js (Joule-seconds) c = 3 × 10^8 m/s (meters per second) λ = 400 nm = 400 × 10^(-9) m (meters) E = (6.626 × 10^(-34) Js × 3 × 10^8 m/s) / (400 × 10^(-9) m) E = 4.969 × 10^(-19) J (Joules) Now, we need to convert the energy from Joules to electron Show more…
