Question

Refractive index of water is 4/3, so apparent depth is__________ the real depth​

Answer 1

Apparent depth is 3/4 the real depth​

Explanation:

As we all know the relationship between the refractive index, real depth and apparent depth is described as

$n=\frac{Real depth}{Apparent deth}$

Where "n" is the refractive index which is equal to the ratio of real and apparent depth.

Now, putting the value of "n" in the formula. We get,

4/3 = real depth / apparent depth

Apparent depth = real depth / (4/3)

So,

Apparent depth = 3/4 (Real depth)
