Question

The phenomenon that leads to the bouncing back of light rays is called-

• A. Diffraction
• B. Reflection
• C. Dispersion
• D. Refraction

Answer 1

The correct option is B Reflection

$Diffraction$ is the phenomenon of bending of light waves around the corners of an obstacle or aperture, placed in the path of light beam.
$Reflection$ is the phenomenon in which light rays on striking a polished surface(such as a mirror) bounce back or are sent back into the same medium.
$Dispersion$ is the phenomenon of splitting of white light into its component colours (VIBGYOR) on passing through a glass prism.

$Refraction$ of light is the phenomenon of bending of light or change in the direction of light, when it passes obliquely from one transparent medium to another.

Hence, the correct answer is OPTION B.
