Thanks guys xx

Hope this helps!!

Good Luck! xx

Answer 2

The photoelectric effect is strong evidence for the particle nature of light as it demonstrates that light can behave like discrete particles (photons) when interacting with certain materials. Additionally, the Compton effect shows that when light interacts with matter, it can transfer momentum to particles, which is more easily explained by the particle nature of light.

Answer 3

there are evidences

brownian motion/movement :is the evidence that molecules of matter exist in continually motion.

Answer 4

Electrons in a beam is deflected by a magnetic field. This is evidence that electrons have a particle-like nature.

Answer 5

The particle nature of light is the only way to explain the "photoelectric effect".

Wrapping up that neat little package won Einstein the Nobel Prize in Physics.
