Answer:
The horizontal distance from the to the bottom of the pool is 3.831 m
Solution:
As per the question;
Height of the pool, H = 1.5 m
Depth of the pool, D = 2.75 m
Refractive index of air,
Refractive index of air,
Angle of the beam at the water surface,
Now,
The angle of incidence is given by
Now, using Snell's law:
Now,
From the normal, the horizontal image distance, d' is given by:
Now,
From the normal, the horizontal object distance, d'' is given by:
Thus the horizontal distance is given by:
d' + d'' = 1.979 + 1.852 =3.831 m
