Question
A water pond appears to be 3 m deep. If the refractive index of water is 4/3, find the actual depth of the pond.

Solution
Apparent depth = 3 m
Refractive Index of water = `4/3, "Actual depth" = ?`
Refractive Index = `"real depth"/"Apparent depth"`
`4/3 = "real depth"/3`
Real depth = `4/3 xx 3`
Real depth = 4 m
