What is the magnification of the image in a microscope using a 20X ocular and a 100X objective? Name and show the equation for the the limit of resolution. What happens to the lr when you use an objective with a lower NA, or light source with a shorter wavelength
(MATLAB example)Write a function that generates an image (a matrix) that contains a circular object with a value of 1 and 0 elsewhere when image size, matrix size, circle center and circle radius are given: function myImage = circle(imageSize, matrixSize, center, radius);
Consider 2 converging lenses of focal lengths 5 mm (objective) and 50 mm. (eyepiece) An object 0.1 mm in size is placed a distance of 5.2 mm from the objective. 1.What is the size and location of the image from the objective? What is the linear magnification of this objective? 2.Treat the image from the objective as an object for the eyepiece. If the eyepiece creates an image at infinity, how far apart are the two lenses? 3.What is the...

C. Producing virtual images The eyepiece of a microscope produces a virtual image to be viewed by the eye, i.e. the rays of light that form the final image diverge from the lens and appear to come from a location behind the eyepiece lens (the image appears to be behind the lens). 1. Make a ray diagram for a converging lens (focal length f) with the object at a distance s < f.
Which answer best describes the image seen through the eyepiece of the telescope?
Which of the following are functions of the eyepiece lens of a refracting telescope? Check all that apply. A to produce an image whose angular size is greater than that of the object B to magnify the image produced by the objective lens C to reverse the orientation of the image produced by the objective lens D to form an image at the focal point of the objective lens What must result if the eyepiece lens of a refracting telescope...
Questions about the eyepieces of telescopes: A) Which of the following are functions of the eyepiece lens of a refracting telescope? (All that apply) (a) to produce an image whose angular size is greater than that of the object (b) to magnify the image produced by the objective lens (c) to reverse the orientation of the image produced by the objective lens (d) to form an image at the focal point of the objective lens B) What must result if...
Consider a microscope that consists of an objective lens and an eyepiece separated by 19.7 cm. The focal length of the objective lens is 0.20 cm, and the focal length of the eyepiece lens is 2.5 cm. Assume the final image is produced at a distance of 25 cm. (a) Find the magnification of the microscope. You may assume that the focal lengths are far smaller than the size of the microscope. (b) Draw a ray diagram for this microscope.
A microscope has an objective lens with a focal length of 19.5 mm and an eyepiece with a focal length of 6.2 mm. With the length of the barrel set an 33.0 cm, the diameter of a red blood cell’s image subtends an angle of 1.2 milli-radians with the eye. The final image distance is 29.0 cm from the eyepiece. (a) What is the length of the image of the of the cell produced by the eyepiece? (b) Using the...
