Quantum Physics

Red has the lowest frequency among visible light colors.

The maximum kinetic energy of the electron is 4.9 eV when the quantum energy is 9.0 eV.

Hertz (Hz) is the SI unit of frequency.

The minimum frequency is called the threshold frequency.

More electrons are emitted in a given time interval.

Quantum physics is the branch of physics that deals with the behavior of matter and energy at the atomic and subatomic levels.

The photoelectric effect is the emission of electrons from a material when it absorbs light or electromagnetic radiation.

The work function is the minimum energy required to remove an electron from the surface of a material.

Frequency is inversely proportional to wavelength; as frequency increases, wavelength decreases.

Energy (E) = h * f, where h is Planck's constant and f is frequency.
