Taylor accidentally dropped a penny on the shallow end of the pool. They know that the depth of the pool is 1 m and it appears that the penny is about 75 cm from the surface of the water. Calculate the index of refraction of the water in the pool.

Explanation:

Given

actual depth of penny

but penny appears 75 cm from the water surface

This is because as the ray travel from denser to rarer medium it bends away from normal so coin appears elevated w.r.t to actual position

Apparent height is given by

Where =Refractive index

H'=apparent height

car stops. he keeps going = he has inertia

answer would be d.) i hope this

explanation:
