An object is placed 18 cm in front of a converging lens that has a 12 cm focal length. Use ray tracing to determine the magnification of the image.

Expert Solution

Please refer to the attached image for the ray tracing diagram and the derivation for the formula for magnification

By following the cartesian system of sign convention -

Object Distance =

Focal length of lens (converging = convex)

Image Distance =

By applying the lens formula -

Thus magnification for the required problem is

The negative sign signifies that the image is real and inverted.

And since

the image is enlarged.

An object is placed 37 cm in front of a converging lens. An image forms which has a magnification of 1.99 and is inverted. The object is then moved to 12.7 cm from the lens. What is the magnification of the image when it is moved there? Include a negative sign if inverted. ***PLEASE ONLY ANSWER IF 100% CORRECT***

An object 5 centimeters high is placed 15 cm in front of a converging lens with focal length 5 cm. Using graph paper (turn the paper so that the long side is horizontal) and a straight edge, draw appropriate rays to locate the image. Chose a scale (tell me what it is!) such that the lens is in the center of the page and the object is near the left side of the page a. Is the image real or...

John has placed an object at infinity. A 20 cm converging lens is nearest to the object. A 10 cm diverging lens is placed 20 cm behind the first lens. Does John have a Galilean telescope? Explain your reasoning. Where is the object placed relative to the objective lens for a microscope? Where is the image formed relative to the objective lens for a microscope? Where is the eyepiece placed for a microscope in order for the relaxed eye condition...
