IT DOESNT USE MIRRORS. IT USE 2*45 DEGREE GLASS PRISMS.THERFORE IT UNDERGOES TOTAL INTERNAL REFLECTION AND REFLECTS TWICE MAKING THE PERSON ABLE TO SEE
Concave
A periscope typically uses two plane mirrors that are parallel to each other. These are called flat mirrors. They are used to reflect light rays and redirect the image. The mirrors are positioned at an angle of 45 degrees to the path of the light.
A periscope does not use concave or convex mirrors. Concave mirrors are curved inward and converge the light rays, while convex mirrors are curved outward and diverge the light rays. In a periscope, the use of flat mirrors ensures that the light rays remain parallel as they reflect off the mirrors.
Regarding the ray diagram of a periscope, it is a bit difficult to draw it using text. However, I can describe it to you. In a periscope, there are two vertical tubes or scope arms connected by a right-angled prism. Light enters one end of the periscope and hits a mirror at a 45-degree angle, then it reflects to the other mirror, and finally exits out the other end.
To create a ray diagram, draw two parallel lines representing the scope arms. At the top of each line, draw a small diagonal line to represent the 45-degree mirror angle. From these points, draw light rays hitting each mirror at a 45-degree angle and reflecting. Make sure the reflected rays are parallel to the original incoming rays. Repeat this process for the second mirror. The final ray should exit parallel to the original incoming light rays.
Remember, it's always helpful to search for images or videos online to better understand the ray diagram of a periscope.
