Why do scientists believe that light is made of streams of particles?

Scientists believe that light is made of streams of particles because only the presence of photons can explain phenomena observed during experiments on the photoelectric effect.

Scientists believe that light is made of waves because experiments have shown that, based on Huygens's principle, waves have the ability to bend and change direction. This behavior of waves explains diffraction and interference.

Answer:

During Photoelectric effect when a photon light particle strikes a metal surface, an electron is ejected, the photon disappears which is a particle.

Explanation:

In quantum physics, light has been taken into both particle and wave nature which is called the idea of wave-particle duality. Depending on which type of experiment is used, light, or any other type of particle, will behave like a particle or like a wave but so far both the aspects of light's nature haven't been completely observed at the same time. We can refer to the Electron Double Slit Experiment to design an experiment to show that light is a particle.
