Question

what is the real depth of a swimming pool when its bottom appears to be realized by 6m?Given refractive index of water is 4/3​

Answer 1

Answer:

Hey!

____________

Real depth of swimming pool =?

Refractive index of water = 4/3

Here,

n = real depth(x) / apparant 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

Answer 2

Answer:

Explanation:

Refractive index= Real Depth

                          Apparent Depth

That is,                

4/3= Real Depth

           6

Therefore real depth

         =4/3 * 6

         = 8 m
