Want this question answered?
A concave mirror is usually used to project something onto a screen. A concave lens is usually used to view an image through the naked eye.
Beacuse the image is formed behind the mirror after reflection. The image appears to be diverging from the Principal Focus.
Virtual
than the rays of the projector will not converge as the concave lens has the characterstic to converge the rays in one place if it converge the rays the image will found on th screen
Eyesight = ------< = the lines are pointing to how it sees. You see things more clearly for far away things> = the lines are pointing to how it sees. You see things more clearly for close objects.Concave: ---------)(> objectConvex: ---------)< objectI hope you understand the answer. I didnt explain it too well.or you could try......concave is like a "cave"..it bends inwardsand convex is just the opposite it bends outwards....//nfjn//....concave mirror is the one which forms the inner part of the spherical mirror or its reflecting surface bulges inwards & convex is the one which bulges outwards. concave always forms real & inverted image while convex forms virtual & erect image
Plane mirrors do not create images that can be placed on a screen, only concave mirrors can.
The way light is reflected is different in a concave mirror depending on the position and distance from the object. when light hits the concave mirror when it is near the object, the rays are scattered and it forms a virtual image, i.e it does not come on the screen. the image will be erect and higly magnified. When it is taken further from the object, the image becomes inverted and real, i.e it can be seen on a screen, and will still be magnified.

A Concave mirror.
nope. bcoz the image is formed behind the mirror.
The screen is curved to correct the focus at the edges. With a large screen, the distance to the edges from the centre is enough to affect the focus from the projector.

If parallel rays (for example sun rays witch are almost parallel) falls on concave mirror, they are gathered at a point, where maximum heat can be generated and it is very small point,witch is called real focus. As we can take it on screen, it is called real focus.
