Sun rays are reflected from a horizontal mirror and falls on a vertical screen .a vertical object of height h is placed on the mirror .length of the shadow on the screen is?

Q. A long horizontal mirror is next to a vertical screen(see figure). Parallel light rays are falling on the mirror at an angle $\alpha$ from the vertical. If a vertical object of height h is kept on the mirror at a distance d $>$ h $tan\left(\alpha \right)$. The length of the shadow of the object on the screen would be.

Q. Rahul switches on a torch and aims it at a mirror held by Anita. The light reflected by the mirror falls on a screen beside Anita. For Rahul, what are the luminous objects among the torch, the mirror, and the screen?

Q.
A rod of height h = 1.25 m is placed vertically on a reflecting surface as shown in figure. Rays from sun cast shadow of rod on wall. Length of shadow on wall is (in meters) (Write upto two digits after the decimal point.)

Q. The plane of a mirror makes an angle ${30}^{\circ }$ with horizontal. If any vertical ray is incident on the mirror, then angle made by the reflected ray on plane mirror will be:-

Q. Two plane mirrors are placed perpendicular to each other. A ray strikes one mirror and, after reflection, falls on the second mirror. The ray, after reflection from the second mirror, will emerge:
