小技巧：

1. 右手拿40R凸鏡，貼近眼睛前面。

2. 左手拿170R凸鏡，手臂彎曲，貼近鏡筒前面。

3. 左手慢慢地往前移動，就可以看到清楚的影像。

Lens system

Objective lens: +170R Convex lens x1

Eyepiece lens: +40R Convex lens x1

Smaller but brighter

HERE’S HOW

. Starting with the setup from Experiment ,

replace the +R Convex lens with the

+R Convex lens.

. Position the lenses  mm apart and

repeat the observation from Experiment ,

slowly moving the eyepiece lens back and

forth until you see a clear image.

WHAT’S HAPPENING

The image is still inverted, but it should appear smaller (less

magniﬁed) and brighter (easier to see).

When you change the distance between the lenses, the image will

become more or less focused.

The farther away the object you are viewing, the closer the two

lenses need to be relative to each other.

Distance

WHAT DO YOU SEE...

For each experiment in this chapter, ask yourself these

questions:

. What is the distance between the objective lens and the

eyepiece lens for the clearest image?

. What is the size of the image that can be seen clearly?

. What is the brightness of the image that can be seen

clearly?
