Question

The real depth of a tank full of water is 4m .find its apparent depth .refractive index of water is 4/3

Answer 1

Answer:

Hey, there!!!

Apparent depth = 3m

Explanation:

FORMULA:

Refractive Index= Real depth÷Apparent depth

GIVEN:

Refractive index (RI) = 4/3

Real depth (r) = 4m

Therefore, apparent depth (a) will be

4/3=4/a

a= (4/4) * 3

a= 1*3

Apparent depth= 3m

Hope this helps.
