We propose a differential interferometer to measure the radius of a concave mirror, in which two phase distributions of the interferograms are measured before and after shifting the concave mirror perpendicular to or along the optical axis, and the radius is calculated from the difference of these ...
A double convex lens is made of glass of refractive index1.55with both faces of same radius of curvature. Find the radius of curvature required, if focal length is20cm. View Solution If the radius of curvature of a concave mirror is 22 cm, what would be its focal length?
The radius of curvature of a concave mirror is 50 cm. Where should an object be placed from the mirror so as to form its image at infinity ? View Solution A Cassegrainian telescope uses two mirrors as shown in Fig. Such a telescope is built with the mirrors 20mm apart. If the radius...
Identify the type of mirror and the relevant mirror formula. For a concave mirror, the mirror formula is, whereis the focal length,is the object distance, andis the image distance. Determine the focal length of the mirror using the radius of curvature. The f...
Calculate the focal length (f) of the concave mirror using the formula for the radius of curvature (R), which is f = R / 2. Use the mirror equation 1/f = 1/do + 1/di to find the image distance (di). Here, do is the object distance (distance ...
Answer to: A plano-convex lens is to have a focal length of 40 cm. It is made of glass of index of refraction 1.65. What radius of curvature is...
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: ...
A new technique to measure the radius of a concave mirror is proposed, in which the radius is calculated from the difference of the two interferograms obtained before and after shifting the sample perpendicular to or along the optical axis. By comparison of these two shifting directions, it is...
The optical mirror system comprises a concave mirror (2) with relatively large curvature radius (R), a convex mirror (1) with relatively small radius, which coaxially faces the concave mirror, and an aperture (S) which defines an object point (O) and an image point (I) at a given ...
The correct Answer is:C To solve the problem, we need to determine the radius of curvature of the curved surface of a plano-convex lens that behaves like a concave mirror when its plane surface is silvered. The given radius of curvature of the concave mirror is 20 cm, and the refractive...
