In the exercise of placing a plastic shopping bag in front the light the observations are;

1. A shadow of the bag is cast on the wall

2. A much smaller shadow is displayed on the wall

3. A small shadow is formed on the wall that is comparatively smaller compared to the ratio of the corresponding sides of the bags

<h3>How does the size of the shadow relate to the size of the bags?</h3>

1. What will be observed when the largest shopping bag is placed between the light and the wall is the shadow of the bag on the wall

2. what will be observed when the second plastic shopping bag which is smaller than the largest shopping bag is placed between the light and the wall is the shadow cast by the bag on the wall which will be smaller than the shadow casted by the largest shopping bag

3. Given that the third plastic shopping bag square is smaller than the other two bags, the shadow cast by it when it is in front of the light will be smaller than the shadow cast by the other two bags

4. the observed difference between the shadows of the three bags is that the shadow are progressively larger as the size of the shopping bag increases.

This is so because the size of the plastic bag and the size of the shadow cast on the wall ars similar shapes, and the dimensions of the image can be obtained by multiplying the lengths of the bag by a scale factor and therefore the ratio of the area of the image to the area of the bag is the square of the ratio of the length of the shadow to the corresponding side length of the plastic bag
