The light is reflected upwards, and passes through the specimen. It passes through easier (clearer) if the specimen is not too thick.
A specimen being viewed under a microscope should be thin so that light can pass through the specimen. The thinner it is the brighter it will be. A thick specimen will block the light and all you'll get is a dark grey image. Also, more detail can be seen in a thin specimen because there will not be parts in front of each other, blocking the view.
Based on other people's answers on other sites, the best answer I got was because the generated light source needs to ba able to shine through the specimen. This allows for better observations and to see individual cells.
Because light must pass through it.

Some microscopes have a mirror under the specimen to reflect room light up through the specimen. Others have a light bulb down there.
Light microscope works because light goes *through* your specimen. So if the specimen is too thick, then light won't shine through, and you won't see anything.
Turn down the light.

The scientist examined the specimen under the microscope.

It is called a diaphram.
tang ina ninyo!!
No, I used light microscopes in my science class and it worked very well.
