Final answer:
When light passes through an aperture, it shows diffraction and interference behaviors typical of waves.
Explanation:
When light passes through a slit or a keyhole, it exhibits a behavior known as diffraction. This phenomenon is a characteristic of waves, where the light spreads out after passing through the aperture instead of just creating a simple shadow. The interference of waves with the slit leads to the pattern observed on the screen.
