Lenard showed that the energy of ejected electrons depends on what property of the incident light?

Polarity
Wavelength
Magnitude
Answer
The wavelength of the incident light determines the energy of ejected electrons. This relationship, known as Lenard's law, is a crucial discovery in understanding the photoelectric effect. Shorter wavelengths, corresponding to higher energy photons, result in greater kinetic energy for the emitted electrons.
