Mirror Equation. Spherical Aberration. Ray diagrams can be used to determine the image location, size, orientation and type of image formed of objects when placed at a given location in front of a concave mirror. The use of these diagrams was demonstrated earlier in Lesson 3.
Spherical Mirror Equation. As in the case of lenses, the cartesian sign convention is used here, and that is the origin of the negative sign above. The radius r for a concave mirror is a negative quantity (going left from the surface), and this gives a positive focal length, implying convergence.
Spherical mirrors may be concave (converging) or convex (diverging). The focal length of a spherical mirror is one-half of its radius of curvature: \(f = \frac{R}{2}\). The mirror equation and ray …
11 sty 2021 · A concave mirror has a radius of curvature of 20.0 cm. Locate the image for an object distance of 40.0 cm. Indicate whether the image is real or virtual, enlarged or diminished, and upright or inverted.
Example 3: An object is placed 10 cm in front of a concave mirror and forms a real image 20 cm from the mirror. Determine the radius of curvature of the mirror. Solution: We use the mirror equation: \(\displaystyle\frac{1}{f} = \frac{1}{d_o} + \frac{1}{d_i}\) Given: Object distance (d o) = 10 cm; Image distance (d i) = -20 cm (negative for real ...
26 sty 2023 · The convex mirror also has a radius of curvature, \(R\), defined as the distance from the mirror to the center of the partial spherical shell. Except, in this case it is on the opposite side of the mirror due to its shape.
