Investigating How the Size of a Shadow Depends on the Angle at Which the Light Hits the Object
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 screen
The results from this are opposite varying the previous factor. In
this case the length of the shadow increased as the distance from the
edge of the object to the screen increased. I expected that as the
distance dubled, the length of the shadow would double but according
to the ray diagram that was not the case. The length of the shadow
The results from this are opposite to varying the previous factor. In
this case, the length of the shadow increased as the distance from the
edge of the object to the screen increased. I expected that as the
distance doubled, the length of the shadow would double but according
to the ray diagrams, that was not the case. The length of the shadow
increased by 1.6 times between changing the distance from 2 cm to 4 cm
(ie:doubling the distance).
In order to make the decision, this report measures the following qualitative and quantitative areas:

Investigating the Effect of Light Intensity on the Size of a Plantain Leaf Title: To investigate the effect of light intensity on the size of a plantain leaf. Hypothesis: I predict that the size of the plantain leaves would increase as the light intensity decreases. Therefore, plantain leaves found in the shade will have larger surface areas than leaves found in an open area. Theory: Sunlight is an essential factor need to complete the process of photosynthesis.

So using this formula but with the data we collected from our first attempt, this is what it would look like; Tan(60°) x 23m = 39m. As you can tell this answer collected from our first attempt is very well incorrect, but at the time, our group did not know this.

...ossessed with three dimensional attributes. The optical effect may be explained by the fact that the human eyes see an object from two viewpoints separated laterally by about six centimeters. The two views show slightly different spatial relationships between near and near distant objects and the visual process fuses these stereoscopic views to a single three dimensional impression. The same parallax view of an object may be experienced upon reflection of an object seen from a concave mirror." (http://www.freepatentsonline.com/4229761.html).
A. Line – An irregular soft line is used to establish the eye level/horizon in background between the sky and the field. The diagonal lines define the field and are in an opposite direction of the diagonal lines that define the trunk off the tree in the middle of the picture. The diagonal lines in the field, the horizon line, and the edge of the painting create a linear perspective.
