Ellen wears eyeglasses with the prescription.
a. What eye condition does Ellen have?
b. What is her far point without the glasses?
A -focal-length converging lens is to the right of a -focal-length converging lens. A -tall object is distance L to the left of the first lens.
a. For what value of L is the final image of this two-lens system halfway between the two lenses?
b. What are the height and orientation of the final image?
Your task in physics laboratory is to make a microscope from two lenses. One lens has a focal length of 2.0 cm, the other 1.0 cm. You plan to use the more powerful lens as the objective, and you want the eyepiece to be 16 cm from the objective.
a. For viewing with a relaxed eye, how far should the sample be from the objective lens?
b. What is the magnification of your microscope?
High-power lasers are used to cut and weld materials by focusing the laser beam to a very small spot. This is like using a magnifying lens to focus the sun light to a small spot that can burn things. As an engineer you have designed a laser cutting device in which the material to be cut is placed behind the lens. you have selected a high-power laser with a wavelength of
your calculation indicates that the laser must be focused to a spot in order to have sufficient power to make the cut. what is the minimum diameter of lens you must install?
A -tall object is to the left of a lens with a focal length of . A second lens with a focal length of is to the right of the first lens.
a. Use ray tracing to find the position and height of the image. Do this accurately using a ruler or paper with a grid, then make measurements on your diagram.
b. Calculate the image position and height. Compare with your ray-tracing answers in part a.
