Question

Please explain all the properties of concave mirror and convex mirror. Also explain the properties of concave lense and convex lense.

Answer 1

convex lenses are thicker in the center that at the edge and concave lenses are thinner in the centre and curved inwards.both the lenses have curved surface.one of the lenses in border in the centre and pointed at the edge while the other is narrow at the centre.A concave lense spread
light and is therefore called a diverging lens.A convex lens converges the light that falls on it and is therefore called a converging

Answer 2

Answer:

placed in front of the mirror. It can be seen that the image is virtual, upright, and diminished. Figure 75: Image formation by a convex mirror.

Image Formation by Convex Mirrors.

Explanation:

When an object is near a plane mirror, the image is erect, virtual and of the same size at the object. A concave mirror gives a magnified and erect image of a nearby object whereas a convex mirror gives an erect and diminished image.

Concave mirrors can produce both real and virtual images; they can be upright (if virtual) or inverted (if real); they can be behind the mirror (if virtual) or in front of the mirror (if real);
