Question
Chapter 2, Problem 7RQ
Summary Introduction
To review:
The increase of resolution with magnification and the ineffectiveness of empty magnification to increase resolution.
Introduction:
The size of the image is enhanced due to the process of refraction which leads to the bending of light after falling on a parabolic shaped eye lens. The process of enhancement of size can lead to better resolution especially in the cases where the object is not resolvable. The phenomenon of refraction is widely depends on the density as well as the thickness of the refractive media.

- What is Fluorescence Reflectance Imaging (RFI)? Explainarrow_forwardWhich of the following is true about the relationship between depth of field and magnification? There is no relationship. When magnification increases, depth of field decreases. When magnification increases, depth of field increases. Stereomicroscopes offer a lesser depth of field than compound microscopes. The depth of field of a microscope determines how much magnification it can achieve.arrow_forwardDefine each of the following terms: A) What is resolution and how is resolution related to the wavelength of light used to illuminate the sample?
