Periscope 2. kaleidoscope Application of the characteristics of images formed by plane mirrors a) b) LESSON ACTIVITY 11 1. A plane mirror has various exclusive features and characteristics corresponding to the image that it forms, which are as follows: A plane mirror always forms a virtual image. The image formed by the plane mirror is laterally inverted, hence the image seen through the periscope is also laterally inverted Answer: False Correct statement: The image formed by the plane mirror is laterally inverted, hence the image seen through the periscope is This is because in periscope, image is reflected by two mirrors. These are used in periscopes and kaleidoscopes, solar cookers, dressing mirrors, etc. In conclusion, plane mirrors produce images with a number of distinguishable characteristics. The overall design of the classical submarine periscope is very simple: two telescopes pointed into each other. Third, we join the light rays from the mirror to the object Such an object is kept out of the observer's line of sight. Two 45-90-45 prisms can be used together to form a periscope. The image formed on a cinema screen is an example of real images. Now,when the reflection is created on the first mirror a lateral inversion happens. Characteristics of the image formed by a Periscope: Therefore, an image formed in a periscope is virtual and without lateral inversion.
