Question

To explain the photoelectric effect, Albert Einstein linked the photoelectric effect to an idea from which scientist?

Answer 1

Based upon Max Planck's theory of black-body radiation, Einstein theorized that the energy in each quantum of light was equal to the frequency multiplied by a constant, later called Planck's constant. A photon above a threshold frequency has the required energy to eject a single electron, creating the observed effect.

Answer 2

Max Planck

Step-by-step explanation:

According to Max Planck light energy is quantized and is released or absorbed as an integer multiple of a small packet of energy which he called a photon. Therefore the energy stored in a photon of light is given by the equation,

E = hV

where E is the energy of the photon, v is the frequency of light and h is the Planck’s constant.

Einstein used the concept of light behaves as photons, discrete energy packets instead of waves to explain the photoelectric effect.
