The focal length of a convex lens is the distance from the center of the lens to the point where the light rays converge. It can be determined by using the lens formula, which is 1/f = 1/u + 1/v, where f is the focal length, u is the object distance, and v is the image di...
1. How do I find the height of an image for a concave mirror? To find the height of an image for a concave mirror, you can use the mirror equation: 1/f = 1/o + 1/i, where f represents the focal length, o represents the object distance, and i represents the image distance. ...
8th order ..., (f) the focal length of the whole system, f1 and f2 the focal lengths of the 1st and 2nd lenses, d1 and d3 the on-axis thicknesses, d2 the air gap, n1 and n2 the refractive indexes, and r4 the radius of paraxial curvature of the 2nd lens on the image plane...

The curvature of the surface is convex rather than being perfectly flat with respect to incident light. This curvature causes parallel rays of light reflecting off the mirrored surface to converge at a point; this point is known as the focal point and produces an inverted image (unless it’s...
