Why is it important to start with the scanning objective in place rather than the high power objective?

Why is it important to start with the scanning objective in place rather than the high power objective?

Because they stay in focus when you change the objective lense. Why is locating an object more difficult if you start with the high-power objective than with the low-power objective? Because the high power brings the object closer so it might be difficult to focus.

Why couldn’t you see a virus with your microscope even if you increased the eyepiece lens magnification to 100x?

It stays in focus when magnification length is changed. Why couldn’t you see a virus with your microscope even if you increased the eyepiece lens magnification to 100x? Viruses are too small to be seen by a light microscope; they can only be seen with an electron microscope with 100,000x magnification.

When you increase the magnification is it necessary to increase or decrease the amount of light?

The light intensity decreases as magnification increases. There is a fixed amount of light per area, and when you increase the magnification of an area, you look at a smaller area. So you see less light, and the image appears dimmer.

How can you distinguish true motility from other movement?

How did you distinguish true motility from Brownian movement or motion of the fluid? Motility is when the organism is moving from point A to point B across the slide; Brownian movement was just a few vibrations/small movements. What is the advantage of the hanging drop procedure over the wet mount?

Which is the best lens to use with immersion oil?

Before using immersion oil, make sure that your 100x objective lens is made for use with immersion oil. Begin by focusing your sample using the 40x objective lens. Rotate the objective lens part way between the 40x and 100x lens so you can reach the cover slip on your slide.

Can you use plan achromat 100X objective lens?

Microscopy image of duodenum captured using Plan Achromat 100x objective lens, with immersion oil. Before using immersion oil, make sure that your 100x objective lens is made for use with immersion oil. Begin by focusing your sample using the 40x objective lens.

What happens when you reduce the refraction of light in a microscope?

If you can reduce the amount of light refraction, more light passing through the microscope slide will be directed through the very narrow diameter of a higher power objective lens. In microscopy, more light = clear and crisp images.

Can you use oil on a 40x lens?

If switching between a dry 40x lens and a 100x oil lens, care must be taken not to get oil on the 40x lens, which could damage it. If you have any questions about using immersion oil with your microscope, contact Microscope World.
