Vedclass · Answer

(A) $1$. The object $O$ is above the principal axis $AB$,and the image $I$ is below the principal axis $AB$. This indicates that the image is inverted.$2$. The distance of the object from the principal axis is $d_1$,and the distance of the image from the principal axis is $d_2$. Since $d_2 > d_1$,the image is magnified.$3$. $A$ convex mirror always forms a virtual,erect,and diminished image. Therefore,the mirror cannot be convex.$4$. $A$ concave mirror can form a real,inverted,and magnified image when the object is placed between the focus $F$ and the center of curvature $C$.$5$. For a real object to form a real image,the mirror must be placed on the side of the object and image. Since the light rays must travel from the object to the mirror and reflect back to form the image at $I$,the mirror must be placed to the right of both $O$ and $I$ (or specifically,to the right of $I$ to intercept the rays). Looking at the geometry,the mirror must be placed to the right of $I$ to reflect the rays from $O$ to $I$.

In the figure shown,the image of a real object $O$ is formed at point $I$. $AB$ is the principal axis of the mirror. The mirror must be:

In the case of a spherical mirror,if the object distance $(u)$ and image distance $(v)$ are measured from the pole,then the graph plotted between $(1/u)$ and $(1/v)$ will be:

An object is placed at a distance of $18 \ cm$ in front of a mirror. If the image is formed at a distance of $4 \ cm$ on the other side,then the focal length,nature of the mirror,and nature of the image are respectively:

For a concave mirror,the $\frac{1}{u}$ versus $\frac{1}{v}$ graph obtained by the parallax method is as shown in the figure. The graph is a straight line with a slope of $-1$. The estimated value of the focal length of the mirror is: (in $cm$)

In an experiment to find the focal length of a concave mirror,a graph is drawn between the magnitudes of $u$ and $v$. The graph looks like:

Assertion $(A):$ The relation among $u, v$ and $f$ for a spherical mirror is valid only for mirrors whose sizes are very small compared to their radii of curvature.
Reason $(R):$ The laws of reflection are strictly valid for plane surfaces but not for large spherical surfaces.
