Answer #1

Concave mirror

When Object placed within the focus,it forms a virtual, upright images,on the other side.

Convex mirror

They always forms virtual diminished upright images.It don't depends on wherever you placed the object.

Concave lens

Like convex mirror they always forms virtual diminished , inverted images.

Convex lens

Like concave mirrors they form virtual images when object placed within the focus.

This image is inverted.

Because a concave lens cannot form a real image of a real object, it is difficult...
Because a concave lens cannot form a real image of a real object, it is difficult to measure its focal length precisely. One method uses a second, convex, lens to produce a virtual object for the concave lens. Under the proper conditions, the concave lens will form a real image of the virtual object! A student conducting a laboratory project on concave lenses makes the following observations: When a lamp is placed 42.7 cm to the left of a particular...

Answer True or False for all statements. The image produced by a convex mirror is always closer to the mirror than it would be in a plane mirror for the same object distance. A virtual image formed by a concave mirror is always enlarged. A concave mirror always forms an enlarged real image of a real object. A convex mirror never forms a real image of a real object. When an object is placed between a concave mirror and its...
