The type of mirror in the given figure.
Answer to Problem 18Q
Solution:
The mirror in the given figure is concave. The person is standing very close to the mirror, which means within the focal length of the mirror and he sees his image,which is an upright and larger virtual image formed behind the mirror. The image of that kind will be given by aconcave mirror.
Explanation of Solution
The concave mirror produces the virtual image and also upright behind the mirror, when the object is placed within the focal length of the mirror, between the center of the mirror and the focal point. This is depicted by the ray diagram as follows.
The man is standing very close to the mirror, which is having a big curvature. As he is very close, he is standing within the focal point of the mirror,the man is between the mirror andthe focal point.
Three rays are considered to describe the image formation.
Ray 1 leaves the tip of man, heading toward the mirror parallel to the axis, and reflects through F.
Ray 2cannot head toward F because it would not strike the mirror; so ray 2 must point as if it started at F (dashed line)and heads to the mirror, andthen is reflected parallel to the principal axis.
Ray 3 is perpendicular to themirror and reflects back on itself. The rays reflected from the mirror diverge andso never meet at a point.
All of the reflected rays appear to be coming from a point behind themirror (dashed lines).This point locates the image of the man. The image is thus behind the mirror and is virtual and upright.

In Module 1 of Course 1, a homework problem asked you to derive the paraxial focus shift along the axis when a slab of glass was inserted in a converging cone of rays. Find or re-derive that result, then use it to calculate the paraxial radius of curvature of a field flattener of refractive index n that will correct the observed Petzval. Assume that the side of the flattener facing the image plane is plano. What is the required radius of the plano-convex field flattener? (p written as rho )arrow_forward

Set the wavelength to the (default) 0.55 microns and a single on-axis field point at infinite object distance. Set the image distance to 200 mm. Make the first surface the stop insure that the lens is fully filled (that is, that the entrance beam has a radius of 10 mm). Use the lens-maker's equation to calculate initial glass curvatures assuming you want a symmetric, bi-convex lens with an effective focal length of 200 mm. Get this working and examine the RMS spot size using the "Text" tab of the Spot Diagram analysis tab (OpticStudio) or the Spd command of the text widnow (OSLO). You should find the lens is far from diffraction limited, with a spot size of more than 100 microns. Now let's optimize this lens. In OpticStudio, create a default merit function optimizing on spot size.Then insert one extra line at the top of the merit function. Assign the…arrow_forward
