Convex mirror has positive focal length. Concave mirror forms a highly diminished sized, real and inverted image of the object at ‘F’ point which can be taken on the screen.Question 23: What is the nature of the image formed by a concave lens? Can this be taken on the screen? Answer...
Magnitude of focal length of convex mirror and concave mirror is f . Then choose the correct options. AMaximum distance of object in event-1 from the mirror is from plane mirror BMinimum distanc of object in event-1 from the mirrro is from convex mirror. CMaximum distance of object in ...
To solve the problem step by step, we need to find the focal length and power of the lens given the height of the object, the height of the image, and the distance of the image from the lens.Step 1: Write down the given data -
Step 1: Understand the mirror equation for a convex mirror. The mirror equation is given by, whereis the focal length,is the object distance, andis the image distance. Step 2: Solve the mirror equation for the image distance. Rearrange the equation to get. S...
These lenses have a positive focal length and near-best-form shape for infinite and finite conjugate applications.Plano-convex lenses can focus a collimated beam or collimate light from a point source. To minimize the introduction of spherical aberration, a collimated light source should be incident...
These dual lenses have a positive focal length and are optimized for infinite conjugation ratios. Double lens pair Achromatic dual lens pairs have the advantages of achromatic lenses and are optimized for finite conjugation. These lens pairs are...
Answer to: A convex mirror with a focal length of -18 cm forms an image 15 cm behind the surface. If the object height is 1.2 cm what is the image...
A converging lens is used to produce an image that is 3 times the size of an object. If the distance between the object and the image is 40.0 cm, what is the focal length of the lens? An object is held 30.9 cm...
A biconvex lens has a convex surface and a double surface, and has a positive focal length. It is usually used for related applications such as beam reduction, focal length reduction, or image enlargement. In order to reduce spherical aberration, the biconvex lens is used to collimate the ...
A plano-convex lens is compose of a plane and convex surfaces, has a positive focal length.It is used for the changing between point light source and parallel beam.It is mean when the light through the convex surface and out from plano surface,the lens will collect ...
