Paano Kalkulahin si Photoelectric
Ano ang Photoelectric?
Photoelectric effect is the emission of electrons when light hits a material. It demonstrates light's particle nature and is used in photodiodes and image sensors.
Pormula
The calculator applies KE_max = hf - φ
Step-by-Step na Gabay
- 1Enter photon frequency and material's work function
- 2The calculator applies KE_max = hf - φ
- 3Results show maximum electron kinetic energy
Mga Nalutas na Halimbawa
Input
f = 6 × 10¹⁴ Hz, φ = 2 eV
Resulta
KE_max = 2.48 - 2 = 0.48 eV
Using h = 4.136 × 10⁻¹⁵ eV·s
Mga Karaniwang Mali na Dapat Iwasan
- ✕Confusing frequency with wavelength in calculations
- ✕Thinking intensity affects electron kinetic energy
Mga madalas itanong
Why doesn't classical physics explain photoelectric effect?
Classical theory predicts increasing light intensity increases electron kinetic energy, but it doesn't—frequency alone matters.
What's threshold frequency?
Minimum frequency for electron emission: f_threshold = φ/h; below this, no emission regardless of intensity.
