Which of the following gives good evidence for the wave nature of EM radiation?

A. matter waves
B. interference patterns
C. existence of photons
D. the photoelectric effect

B. interference patterns

Did you know?

Did you know that interference patterns provide strong evidence for the wave nature of electromagnetic (EM) radiation? When the peaks and troughs of two waves align, they reinforce each other and produce a bright spot called constructive interference. Conversely, when the peaks and troughs are out of sync, they cancel each other out, resulting in dark spots called destructive interference. This phenomenon, commonly observed in light passing through slits or reflected off surfaces, demonstrates the characteristic behavior of waves. While other options like matter waves, the existence of photons, and the photoelectric effect also relate to the wave-particle duality of EM radiation, interference patterns specifically highlight its wave-like nature.
