Concept explainers
(a)
To determine:
The type of the microscope that you use to study (a) the change in shape of a living white blood cell and (b) the details of surface texture of a hair.
Introduction:
Microscope is an instrument that is used to see objects that are not visible from the naked eyes. It was first used by scientist of Renaissance. There are three important parameters in microscopy which are magnification, resolution and contrast.
To determine: The type of the microscope that you use to study the change in shape of a living white blood cell.
(b)
To determine: The type of the microscope that you use to study the details of surface texture of a hair.

- 1.Why is wavelenth the main limiting factor on limit of resoltuin in light microscopy? 2.Assuming that all other variables remain constant, explain why light of shorter wavelengths will produce a clearer image that light of longer wavelenths. 3. Why aren't the magnification of both ocular lenses of a binocular microscope used to calculate total magnification?arrow_forwardPhase contrast microscopy - Human Cheek Cells a. b. What is the basic principle of image formation using this microscopy technique? What can be observed and concluded from the image of the specimen?arrow_forwarda) Briefly discuss the limits of resolution in optical microscopy? b) What is empty magnification? c) What are chromatic and spherical aberration?arrow_forward
