Threshold Frequency and Photoelectric Effect
The threshold frequency is the minimum frequency of light required to eject electrons from a metal surface in the photoelectric effect. Below this frequency, no electrons are emitted regardless of the intensity of the light.
Photoelectric Effect Explanation
- When light of a certain frequency falls on a metal surface, it can eject electrons from the metal.
- The energy of the ejected electrons, known as photoelectrons, depends on the frequency of the light.
- If the frequency of the light is above the threshold frequency for the metal, electrons are emitted with kinetic energy.
- The kinetic energy of the photoelectrons is given by the equation: KE = hf - φ, where KE is the kinetic energy, h is Planck's constant, f is the frequency of the light, and φ is the work function of the metal.
Given Scenario
- In this case, when the metal is irradiated with light of frequency 1.2 x 10^16 Hz, the photoelectrons emitted have twice the kinetic energy compared to when irradiated with light of frequency 1 x 10^16 Hz.
- This implies that the second frequency is above the threshold frequency of the metal, while the first frequency is below the threshold frequency.
Conclusion
- The threshold frequency is the minimum frequency required to eject electrons from a metal surface in the photoelectric effect.
- If the frequency of light is below the threshold frequency, no electrons are emitted.
- The given scenario demonstrates the importance of the threshold frequency in determining the behavior of photoelectrons emitted from a metal surface.
