WAEC Physics 2014 Objective — Question 33

Question 33 of 50 from the West African Examinations Council (WAEC) Physics 2014 Objective paper, with the correct answer and a full explanation.

A fish inside a pond appears to be at a depth of 1.5m when viewed vertically from above. The refractive index of the water in the pond is 1.3. Calculate the apparent displacement of the fish.

A. 2.50 m
B. 1.95 m
C. 1.50 m
D. 0.45 mCorrect

Explanation

Real depth = apparent depth × n = 1.5×1.3 = 1.95m. Apparent displacement = real depth − apparent depth = 1.95−1.5 = 0.45m.
