Show hintHide hint
Think about how light travels through the water to the air.
Question 2.
What is a lens?
Show hintHide hint
Consider how lenses help you see better.
3Question 3.
What is the effect called when objects appear shallower in water?
- Refraction
- Mirage
- Apparent Depth
Show hintHide hint
It's an optical illusion caused by refraction.
4Question 4.

Show hintHide hint
Consider how lenses are used in glasses and cameras.
Question 5.
If a swimmer is looking at a fish underwater at an angle of 30 degrees while swimming at an angle of incidence of 45 degrees, calculate the apparent depth of the fish if the refractive index of water is given as 1.33.
Show hintHide hint
Remember the equation: sin(i)/sin(r) = n.
