Question

what is the real depth of a swimming pool when its bottom appears to be realized by1m?Given refractive index of water is 4/3​

Answer 1

Real depth of swimming pool =?

Refractive index of water =4/3

Here,

n = real depth(x) / apparent depth(y)

x= ?, (x-y) =1 m

n=4/3

n=x/y

n-1 = x/y-1

n-1 = x-y/y

4/3-1 = 1/y

y = 3

Now from,

x-y = 1

x = 1+y

x = 1+3

x = 4m

Thus real depth of swimming pool = 4 m.
