The light goes straight. If so, are they particles? But it is both a particle and a wave.

In Thomas Young's double slit experiment, the phenomenon of interference fringes was
suggested as the basis for light waves.

But Einstein interpreted it as a particle as a phenomenon in which an electron pops out
when a photon collides with electrons in an atom.

Einstein thought that the interference fringes were due to the photoelectric effect that
many photons influence each other.

However, even though only one shot was fired, interference fringes appeared.

So, as a result of detailed observation, the photon was in the form of a particle that
only passed through one hole at this time.

The only difference to this is the difference in whether or not observations were made.

If there is no observer, it is a wave. However, when observed, it is a particle.
