WebIn general, there are two types of spherical lenses. So, lenses formed by binding two spherical surfaces bulging outward are known as convex lenses, while the lenses formed by binding two spherical surfaces such that they are curved inward are known as concave lenses. This is one of the basic differences between concave and convex lenses. WebA spherical mirror, on the other hand, forms either a real or a virtual image depending on the distance between the object and the mirror and its curvature, concave or convex. 12. A concave spherical mirror has a focal length of 12cm. What is the position of the image if an object is placed 18cm in front of it? Answer: kahatduganhambolougs
