Energy planck constant equation
WebLab 11: Planck’s Constant. The objective of this lab is to investigate Planck’s equation for the energy of a photon: E = h·f. You will use light emitting diodes (LEDs). LEDs are semiconductors that emit electromagnetic radiation with visible and near visible frequencies when a voltage is applied to them. WebFeb 21, 2024 · Planck’s equation can also be expressed as, λ E = h c λ — — ( 1) Where λ is the wavelength of radiation. Also, E can be expressed in terms of momentum as, E = pc——– (2) Where P = momentum (Kg m/s) and c is the speed of the light. Using equations (1) and (2) we can conclude that, λ h c λ = p c. or, λ h λ = p.
