The formula for calculating the radius of a concave/convex mirror is R = 2f, where R is the radius and f is the focal length.
The focal length of a concave/convex mirror can be determined by measuring the distance from the center of the mirror to the focal point. This can be done by placing an object in front of the mirror and moving it until a clear, focused image is formed on the other side of the mirror. The distance between the object and the mirror is equal to the focal length.
A concave mirror curves inward, meaning the reflective surface is on the inner side of the curve. This type of mirror reflects light inward, creating an enlarged and upright image. A convex mirror curves outward, meaning the reflective surface is on the outer side of the curve. This type of mirror reflects light outward, creating a smaller and upright image.
The radius of a concave/convex mirror affects the size and orientation of the image formed. A shorter radius (smaller mirror) will produce a larger and upright image, while a longer radius (larger mirror) will produce a smaller and inverted image.
Yes, both the radius and focal length of a concave/convex mirror can be negative. A negative radius indicates a concave mirror, while a negative focal length indicates a convex mirror. This can occur when the mirror is curved in the opposite direction, resulting in an inverted image.
