• A. The process where the incident light on a surface is bounced back into the same medium
• B. Splitting of a ray of light into its 7 constituent colours is known as diffraction
• C. The process by which a beam of light is spread out as a result of passing through a narrow aperture or across an edge,is known as diffraction
• D. None of these

Answer 1

The correct option is C The process by which a beam of light is spread out as a result of passing through a narrow aperture or across an edge,is known as diffraction

Diffraction is the process by which a beam of light or other system of waves is spread out as a result of passing through a narrow aperture or across an edge, typically accompanied by interference between the wave forms produced.
