a)What is the condenser lens on a compound microscope, and how can it affect your view of your specimen? b)Calculate the total magnification when looking through the 40X lens on the compound microscope. c) Describe the process to get a specimen into view using the 40X objective starting from the point after you have plugged in your scope and cleaned the objectives and slide.

Define each of the following terms:  A) What is resolution and how is resolution related to the wavelength of light used to  illuminate the sample?  B) What is the magnification of the specimen if you are using a 40x objective and a 10x  eyepiece?  C) How is the numerical aperture (NA) of a lens related to its ability to gather light from a  specimen?

If the ocular lens of a microscope has 10X magnifying power, and the 40X objective lens is being used for observation, what is the total magnification for the viewed image? 10x 43x 1000x 400x

If the total magnification of a microscope is 700X and the ocular lens magnifies by a factor of 10x, what is the magnification of the objective lens that was used? Paragraph BIU

What is the the total magnification of a microscope that is set up using a 10x ocular lens and a 20x objective lens? Paragraph BIU

The following questions talk about increasing magnification in microscopes. Please answer questions 1 and 2 After a specimen is in focus, where in the field of view should position the specimen before increasing the magnification (be precise)? (QUESTION 2 HAS TWO PARTS TO IT): To increase the magnification, which objective should you click into position next?  After refocusing the specimen with the new objective, if you want to increase the magnification even more, which objective should you now click into position?

State the function of each part of the compound light microscope.

Complete Table 1 below by supplying the characteristics of each objective. Table 1. Numerical characteristics of microscope objectives. LPO НРО OIO Focal length (mm) Working distance (mm) Linear magnification (X) Numerical aperture (N.A..) Features (color of the band, diameter of the opening of the lens, etc.)

In light microscopy, when magnification is increased, the lens focuses closer to the sample.  This makes the user more likely to ram the sample into the lens.  Why is it common for the lens to focus closer to the sample at higher magnifications? What can be done to mitigate this risk?

What is the viewing field diameter when you use 10X magnification on the dissecting microscope
