THE PRACTICE STUDIO
Go slowly. Ask why. Make it yours.
PRACTICE / Snell law
A coin looks closer to the surface
A coin lies 0.24 m below a flat water surface. Water has refractive index 4/3 relative to air. View nearly normally from air.
Find its apparent depth.
Organize the givens & assumptions
- real depth = 0.24 m
- nwater/nair = 4/3
Flat water-air surface, near-normal viewing from air and a point object in water; index ratio 4/3.
- A
- B
- C
