You placed an object and a viewing screen at fixed positions in a horizontal plane. You then placed a convex lens and are allowed to move the lens anywhere in between these two. Assuming that the value of the focal length allows images to be formed, how many distinct, sharp image/s can be formed on the viewing screen?
The solution is given below.
Thank you.

An object and a screen are separated by 27.00 cm. A convex lens is placed between them, 15.00 cm from the object. In this position it causes a sharp image of the object to form on the screen. What is the focal length of the lens, in centimeters?
A bright object and a viewing screen are separated by a distance of 85.0 cm. At what distance(s) from the object should a lens of focal length 15.5 cmcm be placed between the object and the screen in order to produce a crisp image on the screen?
A bright object and a viewing screen are separated by a distance of 89.0 cm . Part A At what distance(s) from the object should a lens of focal length 17.0 cm be placed between the object and the screen in order to produce a crisp image on the screen? Express your answer using three significant figures. If there is more than one answer, enter your answers in ascending order separated by commas.
A man is placed 20 cm to the left of a concave lens of focal length 20 cm. If a convex lens is placed 50 cm to the right of the first lens, the screen must be placed 60 cm to the right of the convex lens for a sharp image of the man be formed on it. What is the focal length of the convex lens?

When an object is placed at the proper distance to the left of a converging lens, the image is focused on a screen 30.0 cm to the right of the lens. A diverging lens with focal length f= -24 cm is now placed 15.0 cm to the right of the converging lens. a) How much do you need to move the screen farther to obtain a sharp image? Indicate if the screen should be moved to the right or to...
Physics Lab:
Place a plane mirror between the converging lens and the screen
(as illustrated). Now move the lens only until a real image is
formed in the plane of the object (recorded as 5cm between the lens
and the object). Look for the image right on the face of the object
mask (image was also located where object is). Compute the focal
length of the converging lens.

1. Image Formation by Mirrors: An object is placed at a distance of 100 cm in front of a convex mirror. A plane mirror is placed at a distance of 40 cm from the convex mirror on the same side as the object. Find the focal length of the convex mirror if the images formed by the two mirrors coincide.
A converging lens of 15cm focal length is placed on an optical bench that is 120cm long. An object fixed at 0.0cm and screen is placed at 140.0 cm. Measuring from the object end of the bench, determine the two positions of the lens for which an image will be focused on the screen. Find all magnification in each case.
