List of formulas related to Quantum Of Light
Photon Energy
h: planck’s constant, f: frequency (Hz), λ: wavelength (m), c: speed of light
$$ E = hf = \frac{hc}{\lambda}(J) $$ $$ = \frac{hc}{\lambda .1,6.10^{-19}}(eV) $$ $$ h = \text {6.625 x }10^{-34} (J.s) $$Condition To Have Photoelectric Effect
Λ: wavelength of the shining light, λo: photoelectric limit, W: emitted work (J)
$$ \lambda \le \lambda_o $$ $$ \lambda_o = \frac{hc}{W} $$Einstein's Equation About Photoelectric Effect
m: mass of photoelectron (kg), vo: maximum velocity of the photoelectron (m/s)
$$ \epsilon = hf = W + \frac{1}{2}mv_o^2 $$
