Why should you watch the objective lens from the side when changing the magnification?
Sometimes, if the stage is set high enough, the objective lens can hit or scratch the slide when it's changed, because each objective lens is a different length. From the back of the microscope, you cannot see if the lens is going to hit the slide or not, and run the risk of disturbing your sample. This problem can be prevented by looking from the side and stopping if it looks like the lens is going to hit the slide.

The magnification ability and clarity of lenses have changed considerably.
What makes the sound of a clarinet?
Sound is produced by blowing through the horn, causing an attached reed to vibrate. By convering or uncovering the holes/keys the pitch is changed from higher to lower.
When the microscope is changed from low power to high power the distance between the objective lens and the cover slip of the slide will?
Decrease.
What lens is changed on a microscope when the magnification is changed?
it has to do with the resolution of the image of the slide obtained...the larger the objective lens value is the greater the resolution it will provide, greater the resolution higher the details.
What is Legolas' objective?
First off, to help Frodo get to Mount Doom to destroy The Ring once and for all. But, after Frodo and Sam went off alone, his objective changed. He then turned to finding and rescuing Merry and Pippin from the horrible Uruk-hai that had taken them captive and were taking them to Isengard.

What is the function of the nose of a microscope?
It holds the objective lens- the lens closest to the slide. A revolving nosepiece holds several lenses, and permits them to be changed easily- changing the degree of magnification

How do you interpret a shadow price of zero?
If there is a shadow price of zero it means it is a non binding constraint and the RHS of the constraint can be changed up to the allowable increase or decrease without changing the value of the objective function.
What was the primary objective of the US naval institute at the time of its founding?
It hasn't changed since its founding - "To provide an open forum for the exchange of ideas, to disseminate and advance the knowledge of sea power, and to preserve our naval and maritime heritage."
Why should you watch from the side before you lower the objective of your microscope?
Sometimes, if the stage is set high enough, the objective lens can hit or scratch the slide when it's changed, because each objective lens is a different length. From the back of the microscope, you cannot see if the lens is going to hit the slide or not, and run the risk of disturbing your sample. This problem can be prevented by looking from the side and stopping if it looks like the lens is going to hit the slide. Watching from the side also helps to know if it is too low, or just in the right distance.
