Q. What does a high power objective lens do?
A high-power objective lens magnifies 40x, with total magnification 400x if the eyepiece lens is 10x power, and it is ideal for observing very fine detail, such as nerve cells in the retina or the striations in skeletal muscle.

Q. Which objective lens should always be used first?
When focusing on a slide, ALWAYS start with either the 4X or 10X objective. Once you have the object in focus, then switch to the next higher power objective.
Q. Under which power is the largest field of view seen on a microscope low or high?
The field of view is largest on the lowest power objective. When you switch to a higher power, the field of view closes in towards the center. You will see more of an object on low power.
Q. At what magnification do you first notice the ragweed pollen?
100x
Q. What is the first step normally taken when you look through the Oculars?
What is the first step normally taken when you look through the ocular lenses? The first step when looking through the ocular lenses is adjusting the light and the objectives.
Q. Why do things look upside down and backwards when you look through the microscope?
There are also mirrors in the microscope, which cause images to appear upside down and backwards. The letter appears upside down and backwards because of two sets of mirrors in the microscope. This means that the slide must be moved in the opposite direction that you want the image to move.
Q. Which Lens is the first magnification step?
What is the first step normally taken when you look through the ocular lenses? The first step when looking through the ocular lenses is adjusting the eye pieces to line up the light is the first step.
Q. What does it mean when an image is inverted in a microscope?
The objective has a very short focal length and creates a larger, inverted image of the object inside the microscope. • Inverted means that the image appears upside down or backward compared with the actual object. • Usually you will find 3 objective lenses on a microscope that are color coded.
Q. What to do when you cant focus?
- Remember the Zeigarnik Effect.
- Use a “daily focus list.”
- Create a “parking lot.”
- Identify your “overwhelm” triggers.
- Go with your flow — not just the flow.
- Look for “positive distractions.”
- Forget perfection.
- Buddy up.
Q. What is the best medication for concentration?
Doctors prescribe medicines like Adderall and Ritalin to treat conditions like attention deficit hyperactivity disorder (ADHD). Sometimes, people who don’t have these conditions take other people’s medicines because they think they’ll help them focus while doing schoolwork.
