A candle is placed between the center of curvature and the focal point of a concave mirror?
Real, Enlargened
What Is the focal point of a concave mirror?
It is the point at which light comes to a focus at a single point in space at a certain distance from the mirror relative to its curvature.
What is the relation of focal length of eye with its curvature?
More the curvature of the eye lens, lesser the focal length is. Lesser the curvature, greater the focal length is
Do concave lenses have negative focal length?
Basically because, in a convex mirror, the curvature is the opposite of that of a concave mirror. It's bevaviour is opposite, too: incoming light is spread out, instead of being focussed.
Explain the difference between the concave mirror and convex mirror?
A convex mirror bulges out. A concave mirror curves inward.For a convex mirror, light rays are reflected to meet at a point, while, for a concave mirror, light rays seem to be reflected from a point. If the incident rays were paraxial, the reflected rays are reflected to meet at, or appear to be reflected to a point referred to as the focal point of the lens. For a convex mirror, the focal point is real, while, that of a concave lens is virtual.
What is the relation between focal length and center of curvature?
The focal length of a concave mirror is about equal to half of its radius of curvature.
If the focal lenght of a concave mirror is 15 cm find the radius of curvature?
The radius of curvature and the focal length mean the same so the radius of curvature is also 15 cm.
The focal point of a concave mirror is 5 cm what is its center of curvature?
10 cm from the mirror.

Why the focal length of concave mirror changes in water?
I don't think so. The focal length would remain the same. It mainly depends on the radius of curvature of the mirror.

Which factor most influences the image produced by reflection of an object on a concave mirror?
The focal point. It can affect size, real/virtual, inverted/upright.
How can a rough value of the focal length of a concave mirror be obtained?
rough focal length of concave mirror
Light from a star is collected by a concave mirror How far from the mirror is the image of the star if the radius of curvature is 150 cm?
The image of the star will be 67.5 cm from the mirror because focal length is the raidus of curvature multiplied by 2 or (2)(C). So, therefore, 150 / 2 will give the focal length which would also be the answer.
