Question

eyeglasses bend light to help the image form properly on the retina. the bending of light as it passes from one medium to another is called
a diffraction
b interference
c reflection
d refraction

Explanation:

To solve this, we analyze each option:

• Option A (diffraction): Involves light bending around obstacles, not medium change. Eliminate.
• Option B (interference): Involves wave interaction, not medium - related bending. Eliminate.
• Option C (reflection): Light bounces off a surface, not passing through media. Eliminate.
• Option D (refraction): Defined as light bending when passing from one medium to another, matching the description.

Answer:

D. refraction
