D+7.5cm Submit D3 Submit The radius of curvature of a sperical mirror is 20 cm. What is its focal length ? View Solution For a plano convex lens, the radius of curvature of convex surface is 10 cm and the focal length is 30 cm. The refractive index of the material of the lens is...
A method and apparatus for controlling the astigmatic focusing of a spherical mirror by adjusting the radius of curvature configuration thereof. Adjustment is made by applying a couple to the outer edge of the spherical mirror. A floating support mechanism prevents distortion of the variable curvature...
The image formed by concave mirror is always real except when the object is placed between pole and focus. The image formed by the convex mirror is always virtual. The radius of curvature is double of magnitude focal length.Answer and Explanation: ...
wavelengths. All light curves show a sudden decrease in flux around the 1,336th integration, simultaneous to a tilt event from one of the segments of the primary mirror20,21. In the NIRISS data, this can be independently identified through a small but detectable morphological change in the ...
Spherical mirrors are reflecting curved surfaces characterized by maintaining a constant distance relative to a curved center. Depending on the sign of the curvature radius, the mirrors are classified as: Concave mirror, if the ...
