Why is a specimen no longer visible when you switch from a low power objective to a high power objective?

You need to re-center it, and refocus. A pain, yes, but it comes with the territory. It is exactly the same with a telescope.

What power do you always begin on when you start looking at something under a microscope?
Actually, it depends on the specimen which you are observing.. Suppose, if you are observing Tissues then you have to switch to 10X objective; but if you are observing mammalian cells or other cellular specimen then you have to switch to 45X objective...But, if you want to observe microbial cells then you have to put a drop a drop of paraffin oil on the smear made on the slide and then observe it into 100X oil immersion objectivelens...
What is the lens that is used to find the specimen on a microscope?
You use the low power lens to find the specimen with a microscope. Once you have found the specimen on low power, you can switch to high power for greater magnification. Just be sure to use only the fine adjustment knobs for focusing on high power so the high power objective won't hit the slide.
What will happen to the light bulb when you switch off the electric circuit?
There will no longer be current to heat the filament which will then cool and no longer emit visible light. While it is cooling it will continue to emit infrared light for a time.
What does it mean when a specimen is under low power magnification you can switch to high power magnification and have the specimen remain in reasonably good focus?
It means you have a good microscope.
How do you switch objectiv?
You switch objective by having a look at your vision or mission or where you would like to go.
What is the switch objective?
A switch can be used to switch on and off electricity. Or switch could mean to switch rails on the railway. Or switch could be to change jobs, task, hobbies, and so on.
Why is it important to focus specimens under the Low Power Objectve before observing it under the High Power Objective?
It allows you to center the specimen, and if it is set up correctly, then when you switch objectives it should still be there and only need fine focusing. It also reduces the chance of crushing the specimen and/or breaking the slide or the lens as the LPO is further away from the slide than the HPO.
What is the proper procedure for focusing the microscope?
start with the lowest objective then adjest your focus. After, switch your objective if needed going from lower to higher
