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.
What is the Focal length of a concave mirror?
It is the point , on the central axis, where light, that is parallel to the central axis, passes thru after it is reflected from the mirror. It is also at a distance from the mirror equal to twice the radius of curvature of the mirror.
Is the length of the diameter always equal to the length of the radius?
The length of the diameter is always twice the length of the radius.
What is the the length of a circle that has a radius of 30?
The circumference of a circle with radius 30 is equal to 2 times the radius times pi, or about 188.5.
How do you find the formula for are of triangle?
the formula for the arc of a triangle is the arc length is equal to the angle times the radius. s=arc length theta=angle made y length of the arc lenth r=radius s=theta times radius
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.
How do you derive relation between focal length and radius of curvature of convex mirror?
For a convex mirror, the focal length (f) is half the radius of curvature (R) of the mirror. This relationship arises from the mirror formula for convex mirrors: 1/f = 1/R + 1/v, where v is the image distance. When the object is at infinity, the image is formed at the focal point, and the image distance is equal to the focal length. Hence, 1/f = -1/R when solving for the focal length in terms of the radius of curvature for a convex mirror.
What is the center of curvature of a 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 distance along the axis from the center of a mirror to a focal point?
The distance from the center of a mirror to the focal point is equal to the focal length of the mirror. This distance is half the radius of curvature of the mirror.
What is definition for the centre of curvature of a spherical mirror?
The center of curvature of a spherical mirror is the point at the center of the sphere from which the mirror is a part. It is located at a distance equal to the radius of the sphere. The center of curvature is an important point for determining the focal length and the magnification of the mirror.
What is the Focal length of a concave mirror?
It is the point , on the central axis, where light, that is parallel to the central axis, passes thru after it is reflected from the mirror. It is also at a distance from the mirror equal to twice the radius of curvature of the mirror.
What is the focal length of concave mirror to form real image?
The focal length of a concave mirror to form a real image is positive. It is equal to half the radius of curvature (R) of the mirror, and the image is formed between the focal point and the mirror.
How would you find the focal point of a convex mirror?
To find the focal point of a convex mirror, you can use the formula: f = R/2, where R is the radius of curvature of the mirror. The focal point of a convex mirror is located behind the mirror, at a distance equal to half the radius of curvature.
True or false the center of curvature of a plane mirror is at infinity?
False. The center of curvature of a plane mirror is not at infinity, but rather it is located at a point behind the mirror at a distance equal to the radius of curvature.
If A Concave Mirror Of Radius Of Curvature cm Produces An Inverted Image 4 Times The Size Of An Object Placed On And Perpendicular To The Axis. Determine By An Accurate Scale The Position Of the objec?
If the image produced is 4 times the size of the object and inverted, then the object is placed at a distance equal to half the radius of curvature from the mirror. This would position the object beyond the center of curvature of the concave mirror. Using an accurate scale, you would measure a distance of half the radius of curvature from the mirror to locate the object.
What is the center of curvature of the mirror?
The center of curvature of a mirror is the point located at a distance equal to the radius of curvature from the mirror's vertex. It is the center of the sphere of which the mirror forms a part. Light rays that are reflected from the mirror and pass through this point are either parallel to the principal axis (for concave mirrors) or appear to diverge from this point (for convex mirrors).
What is Focal length of a concave mirror?
It is the point , on the central axis, where light, that is parallel to the central axis, passes thru after it is reflected from the mirror. It is also at a distance from the mirror equal to twice the radius of curvature of the mirror.
