Formula of radius of curvature of double convex lens?
The formula for the radius of curvature (R) of a double convex lens is given by R = 2f, where f is the focal length of the lens. The radius of curvature is the distance from the center of the lens to the center of curvature of one of its curved surfaces.
Do convex lenses have negative focal length?
No, convex lenses have positive focal lengths. The focal length is the distance from the lens to its focal point where light rays converge. In convex lenses, parallel light rays are focused to a point on the opposite side of the lens, resulting in a positive focal length.
The image produced by a convex lens depends on what?
The image depends on the distance the object is from the lens.
If an object is placed at a distance greater than twice the focal length of a convex lens what type of an image will be produced?
If an object is placed at a distance greater than twice the focal length of a convex lens, a real and inverted image will be produced. The image will also be smaller than the object.
What are the equations used to calculate the focal length and image distance of a plano-convex lens?
The equations used to calculate the focal length (f) and image distance (d) of a plano-convex lens are: For focal length (f): 1/f (n - 1) (1/R1) where: f is the focal length of the lens n is the refractive index of the lens material R1 is the radius of curvature of the curved surface of the lens For image distance (d): 1/f 1/do 1/di where: do is the object distance from the lens di is the image distance from the lens These equations are fundamental in understanding the behavior of light passing through a plano-convex lens.

How do you derive relation between focal length and radius of curvature of convex mirror?
For a convex mirror, the focal length (f) is half the radius of curvature (R) of the mirror. This relationship arises from the mirror formula for convex mirrors: 1/f = 1/R + 1/v, where v is the image distance. When the object is at infinity, the image is formed at the focal point, and the image distance is equal to the focal length. Hence, 1/f = -1/R when solving for the focal length in terms of the radius of curvature for a convex mirror.
How factors affect the magnification of a convex lens?
The magnification of a convex lens depends on its focal length and the object distance from the lens. Increasing the focal length or decreasing the object distance will usually increase the magnification. The magnification is also affected by the size of the object being viewed and the optical properties of the lens itself.
How thickness effects on focal length of convex?
As the thickness of a convex lens increases, the focal length decreases. This is because a thicker lens has a more curved surface, which causes light to converge more quickly. The focal length is the distance at which the light converges, so a thicker lens leads to a shorter focal length.
The distance between a mirror and its focal point is called the?
Focal length, positive number with a concave mirror, negative for a convex mirror.
The image produced by a convex lens depends upon?
The image produced by a convex lens depends upon the object distance from the lens, the focal length of the lens, and the type of object being viewed (real or virtual). The characteristics of the image, such as its size, orientation, and location, are determined by the lens formula and the properties of the convex lens.
How do focal length changes as a convex lens becomes flatter?
As a convex lens becomes flatter, its focal length increases. This is because a flatter lens bends light rays less, causing them to converge further away before focusing, resulting in a longer focal length.
