Question

apparent depth of the fish is 6 cm. determine real depths if refractive index of water is 4/3​

Answer 1

Explanation:

Is this the answer or wrong

Answer 2

Answer: Real depth of fish is 8cm

Explanation:

Apparent depth of the fish is given=6cm;

refractive index=4/3

Refractive index is defined as the ratio of real depth and apparent depth.

RI= real depth/apparent depth.

⇒real depth =RI*apparent depth

⇒real depth =  $\frac{4}{3}*6=8cm$.
