Drawing Ray Diagrams

To do this exercise you will need to print the blank ray diagrams.
Click here for the diagrams. (Once it loads, push control P to print it.)

You will also need a straight edge (like a ruler).
You will be drawing the ray diagrams step-by-step with this quiz.
1. Ignore. Click the next button above.
We start with diagram 1 on your paper.

What kind of device is this?
1. Convex lens
2. Concave lens
3. Convex mirror
4. Concave mirror
Is a convex lens convergent or divergent?
1. Convergent
2. Divergent
As a convergent device, does it have a real or virtual focal point?
1. Real
2. Virtual
Draw your first ray. Click on the next button when finished.
1. Ignore. Click the next button above.
Continue ray 1.
1. Ignore. Click the next button above.
Draw ray 2.
1. Ignore. Click the next button above.
Locate and draw the image.
1. Ignore. Click the next button above.
Is the image magnified or reduced?
1. magnified
2. reduced
Is the image real or virtual?
1. real
2. virtual
Is q + or −?
1. +
2. −
Move to diagram 2 on your paper.

What kind of device is this?
1. Convex lens
2. Concave lens
3. Convex mirror
4. Concave mirror
Is a concave lens convergent or divergent?
1. Convergent
2. Divergent
As a divergent device, does it have a real or virtual focal point?
1. Real
2. Virtual
Draw ray 1.
1. Ignore. Click the next button above.
Continue Ray 1
1. Ignore. Click the next button above.
Draw Ray 2
1. Ignore. Click the next button above.
Locate and draw the image.
1. Ignore. Click the next button above.
Is the image magnified or reduced?
1. magnified
2. reduced
Is the image real or virtual?
1. real
2. virtual
Is q + or −?
1. +

1. Convex lens
2. Concave lens
3. Convex mirror
4. Concave mirror
Is a concave mirror convergent or divergent?
1. Convergent
2. Divergent
As a convergent device, does it have a real or virtual focal point?
1. Real
2. Virtual
Draw your first ray.
1. Ignore. Click the next button above.
Continue Ray 1
1. Ignore. Click the next button above.
Draw Ray 2
1. Ignore. Click the next button above.
Locate and draw the image.
1. Ignore. Click the next button above.
Is the image magnified or reduced?
1. magnified
2. reduced
Is the image real or virtual?
1. real
2. virtual
Is q + or −?
1. +
2. −
Go to diagram 4.
Draw Ray 1.
1. Ignore. Click the next button above.
Continue Ray 1
1. Ignore. Click the next button above.
Draw Ray 2.
1. Ignore. Click the next button above.
Locate and draw the image.
1. Ignore. Click the next button above.
The image is obviously virtual and reduced.
Is q + or −?
1. +
2. −
Move on to diagram 5.
Draw Ray 1 and this time the entire way.
1. Ignore. Click the next button above.
Again, as a convex mirror it is convergent and any parallel rays (like ray 1) will go thru the real focal point.

Draw Ray 2.
1. Ignore. Click the next button above.
Locate and draw the image.
1. Ignore. Click the next button above.
If you were not able to do all of these correctly, begin again.
1. Ignore.
