Question

If diffraction is observed for some phenomenon, it is evidence that the phenomenon is a wave. Does the reverse hold true? That is, if diffraction is not observed, does that mean the phenomenon is not a wave?

a. Yes, diffraction is conclusive evidence of the wave nature.
b. No, the absence of diffraction does not rule out the wave nature.
c. Yes, only waves exhibit diffraction.
d. No, both waves and particles can exhibit diffraction.

Answer 1

If diffraction is observed for a phenomenon, it is evidence that the phenomenon is produced by waves. However, the absence of diffraction does not necessarily mean that the phenomenon is not a wave.

Step-by-step explanation:

If diffraction is observed for a phenomenon, it is evidence that the phenomenon is produced by waves. However, the absence of diffraction does not necessarily mean that the phenomenon is not a wave. Diffraction is a wave characteristic that occurs for all types of waves, so if diffraction is not observed, it does not rule out the possibility that the phenomenon is still a wave.
