Answer
Electron diffraction provides clear evidence for the wave nature of electrons. This phenomenon occurs when electrons are passed through a thin material, resulting in a diffraction pattern, similar to light waves passing through a slit.

Answer
The photoelectric effect demonstrates the particulate nature of light, showing that light can be thought of as consisting of particles (photons) that can eject electrons from a material upon absorption of energy.

Answer
Thus, the correct row that gives evidence for the wave nature of electrons and the particulate nature of light is: C - electron diffraction (for electrons) and photoelectric effect (for light).
