h-Bar -- from Eric Weisstein

WebThe energy E of each quantum, or each photon, equals Planck's constant h times the radiation frequency symbolized by the Greek letter nµ, ν, or simply E = hν. E = hν. E - the energy of each quantum (the energy of a photon) h - Planck's constant - 6.6262 x 10⁻³² J⋅s. ν - the radiation frequency. WebPlanck found the formula he had struck two months earlier. He added further proof of the value of his formula by using it to test the constant h (his value was 6.55 × 10-27 erg-second, close to the modern value of 6.626 × 10-27 erg-second). Therefore, he derived the formula to calculate the energy of the radiation. WebPlanck's constant, in science, is denoted by h, and is given the value of. h ≈ 6.63 ⋅ 10−34 J ⋅ s.
