Focal length, positive number with a concave mirror, negative for a convex mirror.
1/object distance + 1/ image distance = 1/focal length
The focal length of a concave mirror is about equal to half of its radius of curvature.
The objects size is not going to change. The image size, however, would.
I don't think so. The focal length would remain the same. It mainly depends on the radius of curvature of the mirror.
The focal length of a concave mirror is half of its radius of curvature. Therefore, for a concave mirror with a radius of 20 cm, the focal length would be 10 cm.
One way to estimate the focal length of a concave mirror is to use the mirror formula: 1/f = 1/do + 1/di, where f is the focal length, do is the object distance, and di is the image distance. By measuring the object distance and the corresponding image distance, you can calculate an approximate value for the focal length of the concave mirror.
The focal length of a concave mirror does not change when held in water because the refractive properties of the mirror do not affect the light passing through it. The focal length is based on the mirror's curvature and not on the medium surrounding it.
As the curvature of a concave mirror is increased, the focal length decreases. This means that the mirror will converge light rays to a focal point at a shorter distance from the mirror. The mirror will have a stronger focusing ability.
The focal length of a concave mirror can be found by using the mirror formula, which is 1/f = 1/do + 1/di, where f is the focal length, do is the object distance, and di is the image distance. By measuring the object and image distances from the mirror, you can calculate the focal length using this formula.
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.
Focal length, positive number with a concave mirror, negative for a convex mirror.
Images in a concave mirror appear inverted because the light rays converge at a focal point in front of the mirror, causing the image to be flipped. This is due to the way the mirror reflects and converges the light rays, creating a real, inverted image.
1/object distance + 1/ image distance = 1/focal length
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.
The focal length of a concave mirror is about equal to half of its radius of curvature.
