Answer 2

Answer:

Explanation:

One

No one can answer the first question. We are not sure what a,b,c,d refer to. But I can tell you want to look for. If you complete the ray diagram shown, and you extend both the blue and red lines until they meet, they should meet to the left of the focus. The image is very large. Redraw the diagram so that you see what I am saying.

Make the object about a cm from the focus.

Make the focal length roughly 4 cm long.

Now make another drawing. Keep the focal distance from the lens about the same.

Make the object  about 1 cm from the lens.

Now put the two rays that you had from the original diagram.

• You should find that the image is still virtual.
• It is still right side up.
• It is smaller than the image of the first diagram.
• It is much closer to the object.
• The image is between the object and   the left focus.

Two

You have the orange ray going to the lens. So far so good. Where it hits the lens, you should draw an orange line from that point to F2. That makes A the answer.

If you want to know where the image is, draw a line from the top of the object to the center of the lens.

The intersect point should be

• to the right of the object and
• to the left of lens.
• The image is smaller than the object
• virtual
• rightside up.
