How does the photoelectric effect support the concept of wave-particle duality? It indicates that atomic energy levels are continuous. B It shows that light can only behave as a wave. It proves that electrons do not have wave-like properties. D It demonstrates that light can exhibit particle-like properties.

## Step 1<br />The photoelectric effect is a phenomenon where electrons are emitted from a material's surface when light is shone on it. This effect supports the concept of wave-particle duality, which is the idea that light can behave both as a wave and as a particle.<br /><br />## Step 2<br />The photoelectric effect demonstrates that light can exhibit particle-like properties. This is because when light hits the surface of a material, it can transfer its energy to the electrons in the material, causing them to be emitted. This is a characteristic of particles, not waves.<br /><br />## Step 3<br />The photoelectric effect does not support the idea that light can only behave as a wave, nor does it prove that electrons do not have wave-like properties. In fact, the photoelectric effect supports the idea that light can behave as both a wave and a particle, which is the essence of wave-particle duality.
