Which of the following situations exemplifies the dispersion property of light?

• The image of the flower in a mirror

• The sparkling glow of the diamond ring

• The swaying movement of coin under water

• The rainbow in the sky after the rain shower

Explain when can diffraction of light occur?

• When photons oscillate in certain directions are absorbed, while others that oscillate in line with the filter pass through.

• when light strikes the boundary between substances at an angle greater than the critical angle.

• when waves spread and bend as they pass through small openings or around barriers.

• when two or more waves overlap or intersect.
