Photon Energy
- E = hf
- E = hc/λ
Determine Planck's constant with LEDs
- LEDs convert electrical energy to light energy
- Photons are emited when the p.d is above the threshold p.d
- Measure minimum voltage required to turn on LED
- The energy transferred by an electron is approximately equal to the energy of the single photon it emits.
- Ve = hf
- Ve = hc/λ
- We can calculate h using this equation
- Ve = hc/λ
- Ve = hf
- The energy transferred by an electron is approximately equal to the energy of the single photon it emits.
- LEDs convert electrical energy to light energy
