Question
A fish in water sees an object which is 33 cm above the surface of water. The apparent height of the object as noticed by the fish is [Take nw=43𝑛𝑤=43 ]
Solution
The apparent height (h') of an object as seen from a denser medium (like water) can be calculated using the formula:
h' = h / n
where:
- h is the actual height of the object (33 cm in this case)
- n is the refractive index of water with respect to air (given as 4/3 or 1.33 in this case)
Substituting the given values into the formula, we get:
h' = 33 cm / 1.33 = 24.81 cm
So, the apparent height of the object as noticed by the fish is approximately 24.81 cm.
