Question

a pond of depth 20cm is filled with water of refractive the index 4/3. Calculate the apparent depth of the tank
​

Answer 1

Answer:REFRACTIVE INDEX=REAL DEPTH/ APPARENT DEPTH

   APPARENT DEPTH=REAL DEPTH/REFRACTIVE INDEX=20*3/4=15 cm

Explanation:if it helps mark as brainliest

Answer 2

Answer:

Depth of the Pond (d) = 30cm

Refractive index (n) = 4/3

Apparent Depth = d/n

= 20/4/3

= 20 × 3/4 ( Resiprocal of 4/3)

= 15 cm

So this is ur answer mate hope this answer will help uh... thanks....
