Multiple Choice

Snell's Law explains why things in water appear distorted. As a wave that is travelling through the air hits another medium, like water, it refracts because......

• The wave travels slower in air than water

• The wave travels faster in the air than water

• The wave stops and bounces off as it hits the water.

• The wave reflects as it hits the water
