Best Answer

You always focus by moving the slide away from the microscope because if you focus towards the microscope you will break the slide since you can't see how close it is when you are looking through the eye piece.....it is very easy to break the slides and the focus wheel adjustment is essentially a geared lever and is much stronger than you think. By the time you realize the slide is touching the microscope it is too late...the slide will already be cracked/broken.

If a thread layers are colored what layer will come into focus first?

Each thread layer comes into focus separately because the specimen is three-dimensional (it has thickness). By moving the fine adjustment knob back and forth, the layers of the specimen will come in and out of focus.


Why must the course adjustment knob be turned forward only while watching from the side?

The course adjustment knob must be turned forward only while watching from the side to ensure that the microscope's objective lens moves closer to the specimen. This allows for focusing on the specimen and achieving a clear image. Turning the knob in any other direction may result in moving the objective lens away from the specimen, leading to an out-of-focus image.


What is the opposite of moving?

The opposite of moving would be not moving. The best opposite would be "stay put" or the similar concepts stay or remain. Another possible antonym is "stop" because it represents the opposite of something stationary that moves: something moving that becomes stationary.


What is the use of the coarse adjustment knob?

The course adjustment moves the stage of the microscope further/closer away from the objective lens (it is used for general focusing), and the fine adjustment moves the objective lens very small distances for finer focusing.

What is the relationship between movement on the stage and movement seen through the lenses?

The movement on the stage is opposite from the movement seen through the lenses. For example: If you move something on the stage left, what you see through the lenses is the "specimen" moving towards the right.
