The basic structure of a straight magnifying glass

Lenses Frames Lenses

convex lens

A transparent lens that is thin at the edges and thick in the middle, like a magnifying glass, is called a convex lens

How to use a magnifying glass correctly?

When using a magnifying glass to observe an object, move the magnifying glass slowly toward the object being observed until the object or its details can be clearly seen.

The function of convex lens

Observe if you put the magnifying glass under the sun, what will you find on the paper?

1. Magnify objects

2. Gather light

Discover the secrets of convex lenses

Can you arrange the following three pieces of equipment in a certain order and discover the secret of the convex lens on the paper screen?

hint:

1. Pay attention to safety and be careful of candle burns.

2. Carefully write down your group’s practices and findings in the record sheet.

Experimental tips:

1. Can the size of the image be changed?

2. Observe the changes in the distance between the candle, convex lens and paper screen and what happens.

Experiment name: Imaging rules of convex lenses

Experimental materials: light concentrator, convex lens, paper screen, candles, matches, etc.

Experimental steps:

1. Place the lit candle, convex lens, and paper screen in sequence on the light gathering base (if there is no light gathering base, fix it on the table) so that they are in a straight line, and the center heights of the flame, mirror, and paper screen are roughly the same. same.

2. Properly adjust the distance between the convex lens and the paper screen. You can see the image of the candle on the paper screen. What does it look like?

Experimental phenomena:

Real images formed by convex lenses are inverted.

When the convex lens is close to the paper screen and far from the candle, a reduced image is formed;

When the convex lens is far away from the paper screen and the candle is close, a magnified image is formed.

What does the size of the image on the paper screen have to do with?

1. When the convex lens is close to ( ), the image on the paper screen is larger.

2. When the convex lens is closer to ( ), the image on the paper screen will be smaller.

Convex lens imaging rules:

The three virtual images formed by plane mirrors, convex lenses and concave lenses are all upright; while the real images formed by convex lens imaging and pinhole imaging are all inverted.

The function of convex lens

1. Magnify objects

2. Gather light

3. Make objects image
