Question

why does a pencil appear distorted when you put it in a glass of water?
refraction
reflection
temperature

Explanation:

When light travels from air (a medium with a lower refractive index) to water (a medium with a higher refractive index), it bends or refracts. This bending of light causes the pencil to appear distorted. Reflection is when light bounces off a surface, which is not the case here. Temperature has no direct relation to the pencil's distorted appearance in this context.

Answer:

refraction
