The photoelectric effect shows:

0.Particle-like behaviour of light
1.Wave-like behaviour of light
2.Both wave-like and particle-like behaviour
3.Neither wave-like nor particle-like behaviour
Explanation

Photoelectric effect can only be explained by treating light as particles (photons), demonstrating the particle nature of light.
