refractive index of themedium ? = sin i / sinr
i = 45 , r = ?
1.33 = sin 45 / sin?
sin? = sin 45 /1.33
? =32.2820 is the angle
ofrefraction .
b) from
thefigure tan
45 = 2.1
/ x
X = 2.1
from which the distance of the person 'x' can bedetermined.
c) if the pool isempty the object must be moved to the distance
d = tan(45 -32.282)* depth of the pool.
