Answer:
Yes humans can directly see a photon.
Step-by-step explanation:
In fact, photons are the only things that humans can directly see. A photon is a bit of light. Human eyes are specifically designed to detect light.
This happens when a photon enters the eye and is absorbed by one of the rod or cone cells that cover the retina on the inner back surface of the eye.
For Example
- When you look at a chair, you are not actually seeing a chair.
- You are seeing a bunch of photons that have reflected off of the chair.
Thus, Yes humans can directly see a photon.
