What is the relationship between the frequency of photons and the ability to remove electrons from a metal?
What is the relationship between the frequency of photons and the ability to remove electrons from a metal?
The frequency of photons must be sufficiently high to break electrons free from a metal.
How can shining a beam of light onto a metal surface be conceptualized?
How can shining a beam of light onto a metal surface be conceptualized?
Shining a beam of light onto a metal surface can be thought of as shooting a beam of particles (photons) at the metal atoms.
What is the condition for the light to have just enough energy to knock the electron loose from the metal?
What is the condition for the light to have just enough energy to knock the electron loose from the metal?
The frequency of photons must be such that hν is exactly equal to the energy that binds the electrons in the metal.
