1/o + 1/i = 1/f
f = (o x i)/(o + i)
f = 11.1 cm (rounded)
1/object distance + 1/ image distance = 1/focal length
A concave mirror bulges away from the incident light. The image of an object depends on where exactly the object is placed - relative the to focal length of the mirror. See the attached link for more details.
40cm
The distance of the object from the mirror line should equal the distance of the image from the mirror line.
Use 1/s + 1/s' = 1/f s = 20cm f = +10cm (positive since the mirror is concave) 1/s'=1/f - 1/s 1/s'=1/10 - 1/20 = 1/20 So, s'=20cm. The distance from the image to the mirror is 20cm, which is not surprising, since the object placed at 1/2 of the focal length and therefore exactly at the radius of curvature point. The image is real and inverted.
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.
1/object distance + 1/ image distance = 1/focal length
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.
In a concave mirror, the relationship between object distance, image distance, and focal length is described by 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. As the object distance changes, the image distance and focal length will also change accordingly.
If an object's distance from the concave mirror is greater than the mirror's focal length, then the mirror image of it will be inverted. If the distance from the concave mirror is less than the focal length of the mirror, the image will not be inverted. No image will be produced if the distance from the mirror to the object is equal to the mirror's focal length.
Sum of reciprocal of object distance and reciprocal of image distance gives the reciprocal of focal length
When using a concave mirror, the object distance (distance of the object from the mirror) can vary depending on where the object is placed. If the object is located beyond the focal point of the mirror, the object distance will be positive. If the object is placed between the mirror and the focal point, the object distance will be negative.
A concave mirror forms a real or virtual image, depending on the object's distance from the mirror and the mirror's focal length.
Distance from the mirror, curvature of the mirror.
The magnification equation for a concave mirror is given by the formula: M = - (image distance) / (object distance), where M is the magnification, image distance is the distance from the mirror to the image, and object distance is the distance from the mirror to the object. Negative magnification indicates an inverted image.
A concave mirror is a curved mirror with reflective surface facing inward. It can form both real and virtual images depending on object distance and focal length. The image formed by a concave mirror can be upright or inverted, magnified or diminished, depending on object position relative to the focal point.
