What is the center of curvature of a plane mirror?
A plane mirror is not curved so it does not have a center of curvature. Or if you want to be mathematically correct, you could say that it's center of curvature is at an infinite distance from the mirror.
What are the properties of images that a concave mirror can produce?
there is an imaginary point in front of the concave mirror, called the focal point or focus, which is half the length of the radius of the sphere of which the mirror was a part of(radius of curvature). usually an object if seen in between the mirror and focus gets magnified, beyond the focus, it gets inverted and reduced.
Images formed by a plane mirror?
A plane mirror forms 1 virtual image and no real image. The virtual image is behind the mirror, at the same distance as the object in front of the mirror, erect, in mirror image left-right.
Where does your image appear to be when you look into a plane mirror?
It's a virtual reflection of the object which appears as an image as much behind the mirror as the distance of the object in front.
Where should the object be placed in front of a concave mirror to form a virtual and magnified image?
between the center of curvature and focus
When you view your in a plane mirror how far behind mirror is your image compared with your distance in front of the mirror?
same distance
If an object 5 millimeters high is located 15 millimeters in front of a plane mirror How far from the mirror is the image located?
The answer is 15 millimeters behind the mirror, and the distance from the actual object to the image is 30 millimeters. Plane mirrors have a flat focus that places the image as far behind the mirror as you are in front of it.
When light strikes the large concave mirror of a reflecting telescope where is the light focus?
In front of the mirror
What is the center of curvature of a plane mirror?
A plane mirror is not curved so it does not have a center of curvature. Or if you want to be mathematically correct, you could say that it's center of curvature is at an infinite distance from the mirror.
Why convex mirror has virtual focus?
The convex mirror diverges light rays, so if you draw the reflected rays in front of the mirror and continue drawing them at the back of the mirror the virtual light rays (at the back of the mirror) will join. This point is called a Virtual Focus Point.

If you take a photo of your image in a plane mirror how many meters away should you set your focus if you are 3 meters in front of the mirror?
6m
If a student stand 2m behind a plane mirror how far is the image?
Since the mirror reflects the image in front of it, the apparent distance of oneself standing in the mirror will be twice as far as the distance from you to the mirror. If you are standing 2 meters from the mirror, the image will appear as 4 meters away.

What is depth of field for micrscope?
The distance in front of and behind the focal point that is in relative focus
What do you see when you stand in front of a concav mirror beyond its focus and look yourself?
you see an inverted real image of yourself
