Sun+Shadows

__SUN SHADOWS__

Because the sun is so far away, any consideration of the height of the light source, as in lamp shadows, would make no sense. We, therefore, will need to consider different factors at work in determining the length of a shadow created by the sun. We will need to use a branch of mathematics called **//Trigonometry//** in order to study the relationship between the angle at which the sun is shining and the length of a shadow.
