An object is placed 13.3 cm away from a convex mirror with a focal length of magnitude 7.00 cm. (a) Is the sign of the focal length negative or positive? (b) Find the image distance q. A concave, spherical mirror and a thin, converging lens are both measured in air (n =...
Positive Focal Length Image can be real or virtual A Bi-concave Lens consists of two inwardly curved surfaces and focal length is negative. It is often used to increase focal length and divergence of light. It can be used in Laser Beam Expanders, Optical Character Readers, Tolerances and ...
A concave mirror produces a real image that is 3 times as tall as the object. If the object is 6 cm in front of the mirror, then what is the focal length of the mirror? Does a concave mirror function as a positive lens? Explain. ...
Focal length of a concave mirror is Apositive Bnegative Cdepends on the position of the objects Ddepends on the position of imageSubmit The focal length of the convex lens is A+10 cm B+20cm C−10cm D−20cmSubmit What is the combined focal length of a convex lens of focal ...
To find the focal length of a combination of a convex lens and a concave lens placed in contact, we can follow these steps:1. Identify the Focal Lengths: - Let the focal length of the convex lens be \( f1 = A \) (positive).
A concave lens is commonly used intelescopes, peephole and eyeglasses. What are the types of convex lens? Types of Convex Lens: Plano-convex Lens: It is curved outwards from one side and the other side plane. It is positive focal length elements that have one spherical surface and one fla...
