A 2cm high object is placed 3cm in front of a concave mirror. If the image is 5cm high and virtual, what is the focal length of the mirror? A 2.50 cm high object is placed 3.5 cm in front of a concave mirror. If the image is 5.0 c...
Is concave mirror converging or diverging? We find that the rays reflect from the concave mirror, and according to the reflection laws the rays converge to a point on the principal axis. The image formed is a real image and this image is formed on the same side of the mirror. Hence, th...
An object is placed 60.0 cm from a concave (diverging) lens that has a focal length with a magnitude of 20.0 cm. A concave mirror with a focal length with a magnitude of 15.0 cm is located 30.0 cm from the lens as shown in the figure. The object is 3.0 cm An ob...
Thus, the surface serves as double-sided mirror, with one of the sides being the concave and one being the convex side. The principal axis, focal point, and center of curvature are shown. The region on both sides of the mirror is divided into eight sections (labeled M, N, P, Q, R,...

A lens is a piece of transparent material having two curved surfaces. A light ray passing through the lens is refracted, i.e. it changes its path of motion. A lens can be concave or convex depending on the shape of the cu...
