Calculate the probable focal length of the convex lens by focussing the image of a distant subject (example: a tree) on a clear screen and calculating the length between the image and the lens. Fix the object needle, the mirror, and the lens on the optical bench as shown in the above figure.
Determining the focal length of a concave mirror and the convex lens for a distant object. Focal length is defined as the distance between the center of the lens or mirror and the focal point of the lens or the mirror
Jan 26, 2023 · We define this point as the focal point of a convex mirror. The focal length has the same relationship to the center as a concave mirror, \(f=R/2\). However, since the the focal point does not focus physical rays, it is a virtual focal point. The same Equation \ref{mirror-eq} applies to convex mirrors.
Jul 5, 2024 · The focal length of a convex mirror can be determined by introducing the convex lens between the object and the convex mirror. With the help of a convex lens side by side with an object, an image can be obtained when the convex mirror reflects the rays along the same path, i.e. when rays fall naturally on the mirror.
Jun 26, 2024 · The mirror formula connects distances of the object and image from the pole of a mirror and the mirror's focal length. Here is the equation relating these three variables: \frac {1} {f}=\frac {1} {v} + \frac {1} {u} f 1 = v1 + u1. where: f f — Focal length of the mirror: the distance between the principal focus and the pole of the mirror.
Jul 5, 2024 · Physics Experiment - An Introduction to Determination of Focal Lengths of Concave Mirror and Convex Lens. We all have used a magnifying glass at some point or the other to enlarge the object we are viewing. Why is it that at a particular point from the glass the object is magnified to the maximum?
Determine the focal length of a convex mirror that produces an image that is 16.0 cm behind the mirror when the object is 28.5 cm from the mirror. See Answer Answer: f = -36.6 cm
The focal point F and focal length f of a positive (convex) lens, a negative (concave) lens, a concave mirror, and a convex mirror. The focal length of an optical system is a measure of how strongly the system converges or diverges light; it is the inverse of the system's optical power.
The distance to the focal point from the mirror is called the focal length. We can see from the figure that this focal length is also equal to half of the radius of the curvature. shows the ray diagram of a concave mirror.
FOCAL LENGTH...NEVER CONSTANT! According to our science textbook focal length(f) of a mirror/ lens is equal to half its radius of curvature(R).Which means that there is a specific focal length for a given lens/mirror(f=R/2).
