Light also consists of particles

In summary, the experiments that led to the realization that light also consists of particles include the photoelectric effect and Planck's blackbody radiation. The photoelectric effect, conducted by scientists such as Albert Einstein, played a significant role in understanding the particle nature of light.

Please read the introductory article at wikipedia.org about photons. Does that help?

i could not find where it says what the first experiments that show light was a paricle?

Try the 2nd paragraph of the article, and section 3 on Historical Development. You can also follow some of the suggested reading out of the article to get more details on the experiments.

so is it the photoelectric effect and plack's blackbody radiation?

Those are good choices. Was there anything special about the photoelectric effect work? Who did those experiments? Did anything special happen to that scientist as a result of the experiments?
 

1. What are the particles that make up light?

The particles that make up light are called photons. They are tiny packets of energy that have no mass and travel at the speed of light.

2. How do photons behave?

Photons behave both like waves and particles. They can travel through space as a wave, but also interact with matter as discrete particles.

3. How do photons create electromagnetic radiation?

When photons are in motion, they create electromagnetic radiation. This includes all types of light, from radio waves to gamma rays.

4. How does the energy of a photon relate to its frequency?

The energy of a photon is directly proportional to its frequency. This means that photons with higher frequencies have more energy than those with lower frequencies.

5. How does the particle nature of light explain phenomena like the photoelectric effect?

The particle nature of light helps to explain the photoelectric effect, where electrons are emitted from a material when light is shined on it. This is because photons with enough energy can transfer their energy to electrons, causing them to be released from the material.
