Explanation Cassegrain telescope is a kind of astronomical telescope where a concave mirror is used as objective and a convex mirror as its eye piece. Parallel rays from the distant star is allowed to fall on the objective mirror and the image of the star is formed at the focus of the concave mirror. This image serves as a virtual object for the convex mirror and the mirror forms its real image. If the electronic sensor is placed at the point where the image is formed, the image of the star can be recorded. The arrangement is as shown below. The focal lengths of the objective f o and the eyepiece f e are related to their respective radii of curvature R o and R e as follows. f o = R o 2 ; f e = R e 2 The image of the star after reflection from the objective is formed at the focus of the mirror. If the mirrors are placed at a distance from each other, then the object distance for the convex mirror is given by, d o e = f o − d The mirror equation is then used to calculate the distance of the image d i from the convex mirror. 1 f e = 1 d o e + 1 d i The sensor is to be placed at a distance d i from the eyepiece mirror. Given: The radius of curvature of objective mirror R o = 3.00 m The radius of curvature of the eyepiece mirror R e = − 1.50 m The distance between the mirrors d = 0.90 m Formula: f o = R o 2 ; f e = R e 2 d o e = f o − d 1 f e = 1 d o e + 1 d i Calculation: Using the given values of the radii of curvature R o and R e calculate the focal lengths of the objective and the eyepiece mirrors...

Lateral Magnification

In very simple terms, the same object can be viewed in enlarged versions of itself, which we call magnification. To rephrase, magnification is the ability to enlarge the image of an object without physically altering its dimensions and structure. This pr…
