Options

• dispersion

• refraction

• reflection

• diffraction

Answer 1

The phenomenon due to which a ray of light deviates from its path while travelling from one optical medium to another optical medium is called refraction.

Explanation:

Refraction is the change in the path of light as it passes from one optical medium to another. Dispersion is the splitting of light into colours, reflection is the bouncing back of light, and diffraction is the bending of light around an obstacle.
