A sailboat's shadow changes to as the distance to the screen varies. Choose all that apply: it changed shape, size, vertices moved along rays, or position.
STEP 1
Assumptions1. The shadow play involves a sailboat and a screen.
. The distance between the sailboat and the screen changes.
3. This change causes to form .
4. We need to determine what changes occurred to .
STEP 2
In a shadow play, the shape of the object (in this case, the sailboat) does not change. Therefore, the shape of did not change. So, the statement "It changed shape" is not correct.
STEP 3
As the distance between the sailboat and the screen changes, the size of the shadow (in this case, ) also changes. Therefore, the statement "It changed size" is correct.
STEP 4
The vertices of correspond to specific points on the sailboat. As the distance between the sailboat and the screen changes, these points move along the rays of light. Therefore, the statement "Its vertices moved along the rays" is correct.
STEP 5
As the distance between the sailboat and the screen changes, the position of the shadow (in this case, ) also changes. Therefore, the statement "It changed position" is correct.
So, the changes that occurred to are- It changed size.
- Its vertices moved along the rays.
- It changed position.
