What is the difference between a concave mirror and a convex mirror?
ShapeConcave mirrors curve inward, creating a focal point in front of the mirror. Convex mirrors curve outward creating a focal point behind the mirror.Concave ImageBecause of their shape and focal point placement, images in concave mirrors appear upside down and far away. However, when you move closer, the object enlarges. If you get close enough, the object enlarges more and the image is right-side up.Convex ImageIn a convex mirror, images appear right-side up, shrunken and virtual, or placed somewhere behind the mirror.
How can you identify the three types of mirrors without touching?
In the plane mirror, our image will be seen as same size of us and erect. In case of concave mirror, our image will be inverted. This is because concave mirror forms real, inverted image when object is placed behind the focus of the mirror. In case of convex mirror, the size of the image will be diminished, or smaller than us and the image will be erect too. This is because the image formed is virtual and erect.
What happens when you move the torch closer to an object?
the shadow becomes bigger
Why bathroom mirror produces only virtual image?
Because when used, the object (your face) is closer to the mirror than the focal length. Move a long way off and things will change.
What happens to an object if you move it closer to a concave lens?
As an object moves closer to a concave lens, the virtual image, that is created on the same side of the lens as the object, will remain upright but will be reduced in size.
What do you observe if you move closer to mirror?
The image get bigger

What happens when an acid and a base are combinded?
They move closer to water (not acidic or basic)
If you freeze a liquid what happens to the particles?
The particles move closer together and are practically so close they cannot move.
Why convex mirrors are used in shopping malls?
Convex mirrors are used as driving mirrors because they give drivers a much larger field of view without needing to move their heads from side to side.

Because when used, the object (your face) is closer to the mirror than the focal length. Move a long way off and things will change.
