Aluminum foil reflects more light
This is called refraction. Some common examples of refraction are a straw appearing bent or cut once it enters water in a glass.
The concepts used to solve this problem are those related to the Pythagorean theorem for which we will calculate the distance and the pitch.
According to the attached diagram we have that the expression of the resulting displacement is

Therefore the resultant displacement of the girl is



Therefore the girl has displaced around of 5 blocks
Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Explanation:
