Question

the refractive index of water is 4 by 3 therefore a swimming pool appears ​

Answer 1

Explanation:

RI=

apparent depth

real depth

Substituting,

3

4

=

2.7

real depth

Therefore, real depth=

3

2.7×4

=3.6RI=

apparent depth

real depth

Substituting,

3

4

=

2.7

real depth

Therefore, real depth=

3

2.7×4

=3.6

Real depth=3.6m

Real depth=3.6m
