WebTwo lenses are placed along the x axis, with a diverging lens of focal length 8.00 cm on the left and a converging lens of focal length 16.0 cm on the right. When an object is placed 10.0 cm to the left of the diverging lens, what should the separation s of the two lenses be if the final image is to be focused at x = ?

WebThis is how far this parallel light ray had to travel. So this is the distance from the image to the lens. And then we have the focal distance, the focal length. And that's just this distance right here. This right here is our focal length. Or, we could view it on this side as well. This right here is also our focal length. sharon kenny homes englandWebThe focal length of a converging lens is the distance from the lens or mirror at which an image is formed the distance from the lens or mirror at which an object is placed the distance from the lens or mirror at which parallel light rays converge the distance from the front surface to the back surface of a lens or mirror the length of the lens itself - A virtual … sharon kessen sturgeon bayWebIf the light rays converge (as in a converging lens), then they will converge to a point.
