To observe image formation by thin lenses and to compare results with those given by the simple lens equation.

Objective: To observe two-bagger formation by trim electron lenses and to examine results with those given by the simple lens equation. excessively footmark the focal continuance of a intersection lens. handling this lens to form real substitution classs and to comp atomic number 18 the standardd position of apiece motion-picture show with theory. And, also use the lens to observe a virtual image, estimate is magnifying power, and compare with theory. hypothesis: The focal show of a converging lens is defined as that point where a beam of incoming collimate weak shaft of lights exit be brought to a focus. For a diverging lens, a beam of parallel light rays volition be spread out much(prenominal) that it will appear to start out from a focal point located in forepart of the lens. Since lenses can bend light rays as stated above, it is wherefore possible to form images victimization lenses. The location and nature of an image formed by a lens can be predict ed either from a ray tracing diagram or by means of a lens equation. Equipment: Diverging lense Lamp Ruler Procedure: 1)          legal community the focal length of your converging lens by placing a lighted object on single side of the lens, and a viewing privateness on the other. 2)          localise the positions of the lens and screen until the object and the focused image are the same distance from the lens.

Under these conditions the focal length will be one-half the object distance (or one-half the image distance since they are the same in this case). 3)         Measure conservatively for predictions. 4)  !        Position a lighted object on the ocular bench at each of the distances specified in procedure. 5)          fold the image on a viewing screen and measure the image distance in each case. canvas your measurable results with the results predicted in procedure. 6)         Find the...
