WebVirtual images are always upright and cannot be projected. Virtual images are larger than the object only in case 2, where a convex lens is used. The virtual image produced by a concave lens is always smaller than the object—a case 3 image. We can see and photograph virtual images only by using an additional lens to form a real image. Webthe distance from the centre of the lens to the principal focus. what are the two rules for refraction in a convex lens? > incident ray parallel to the axis refracts through the lens and passes through the principal focus on the other side. > an incident ray passing through the centre of the lens carries on in the same direction.

WebMagnification is a measure of how much larger a microscope (or set of lenses within a microscope) causes an object to appear. For instance, the light microscopes typically used in high schools and colleges magnify up to about 400 times actual size. So, something that was 1 mm wide in real life would be 400 mm wide in the microscope image. WebThere would be. By definition, the focal point of a lens is the point where two or more rays parallel to the principal axis gets focused. Even if the lens' curvature is not circular, it can focus the light rays to a point. It's just an assumption, for the sake of simplicity.
