Symbolism of Blood in Macbeth

Introduction
The aim of the project is to see which factors affect the size of a shadow and then to look more closely at one of the factors to see how exactly it varies the size of a shadow.

Variables that may affect the size of the shadow

Although, I will investigate how one factor affects the size of a shadow, there are other factors that could be investigated. Here are some examples:

1) The distance between the light and the object












From the ray diagrams I can see that as the distance from the object to the light source is doubled, the length of the shadow decreases. A distance of 4cm produces a shadow of approximately 1.6-cm. Decreasing the distance to 2cm(half the distance), the shadow size increases by one and a half times to produce a shadow of 2.3 cm. The three ray diagrams together show the increase of the distance between the object and light source, decreasing the length of the shadow.

2) The distance between the object and the s...
