What happens when a lens is cut horizontally? If a convex lens is cut horizontally from optical axis i.e., from middle, then radii of curvature on both sides of the lens i.e., R1 and R2 will remain same as before. As R1 and R2 do not change, so there will be no change in focal […]

At what distance from a converging lens of focal length 12 cm and object is placed in order that an image of magnification 1 will be produced? Magnification 1 means that the image distance is the same as the object distance and the size of image is the same as the object. This happens only […]

How do you reduce voltage in a generator? Adjust the throttle of the generator to increase or decrease RPMs of the machine’s motor. Slowing the RPMs decreases the voltage output; increasing RPMs increases the voltage output. The throttle is normally located on the top or side and has RPM written on it. What is the […]
