The two periscopes differ in the way they erect the image. Old trench periscopes worked by using two mirrors to bounce light from one place to another. a Mirrors b Prisms c Observer's eye Principle of the lens periscope. The periscope is an instrument for observation, It consists of a tube with mirrors at each set parallel to each other at a 45-degree angle, with the addition of two simple lenses, and it depends on the occurrence of regular light reflection on the plane mirrors.. At the bottom of the periscope, the light strikes another mirror and is then reflected into the viewer's eye. the principle of periscope works on reflection of light rays.in this light rays reflect from one mirror to another mirror that is opposite to that mirror placed upsidedown placed in any safe object. A periscope works on the principle of : This objective type question for competitive exams is provided by Gkseries. Light reflected from an object enables us to see the object when it is in the line of sight. … NULL. Old trench periscopes worked by using two mirrors to bounce light from one place to another. Few important drawbacks of using the periscopes are its size, height and that it can allow only one person to view at a time. A periscope is an optical instrument that uses a system of prisms, lenses, or mirrors to reflect images through a tube. When light falls on one mirror, it is reflected back and falls on the other mirror and gets reflected to the observer’s eyes. The light bounces from one to the other and then out to the persons eye. A periscope works on the principle of total internal reflection of light. This device consist of two lenses for the purpose of clear vision.
