Question

which two options are examples of waves refracting?
a. a voice echo
b. your image in a mirror
c. an object appearing broken when partly seen through water
d. light bending as it travels through glass

Explanation:

• Option A: A voice echo is an example of sound wave reflection, not refraction. When sound waves hit a surface and bounce back, it creates an echo.
• Option B: Your image in a mirror is due to light reflection. Light rays bounce off the mirror surface to form an image.
• Option C: An object appearing broken when partly seen through water is because of light refraction. Light bends as it moves from water (a medium with one refractive index) to air (a medium with a different refractive index).
• Option D: Light bending as it travels through glass is also an example of refraction. The change in the medium (from air to glass) causes the light to change its direction.

Answer:

C. An object appearing broken when partly seen through water, D. Light bending as it travels through glass
