Photo energy wavelength
WebFeb 20, 2024 · Photon energy is given by (29.2.3) E = h f Since we are given the wavelength rather than the frequency, we solve the familiar relationship c = f λ for the frequency, yielding (29.2.4) f = c λ. Now substituting known values yields E = ( 6.63 × 10 − 34 J ⋅ s) ( 3.00 × 10 8 m / s) 420 × 10 − 9 m = 4.74 × 10 − 19 J.
