What are multiple images Class 8?
Multiple Images: When two or more mirrors are placed at some angles to each other, we get to see multiple images. If an object is placed between them, its image is formed in both the mirrors. The image in one mirror would act as an object for another mirror and this sequence would continue.
Who gave the concept of group?
Development of permutation groups One foundational root of group theory was the quest of solutions of polynomial equations of degree higher than 4. . For simple cases, the problem goes back to Johann van Waveren Hudde (1659).
What do you mean by multiple images?
Multiple images are the images that are formed when two or more mirrors are placed infront of each other and an object is placed between them.
What kind of image is formed due to regular reflection?
Regular reflection occurs when light reflects off a very smooth surface and forms a clear image. Diffuse reflection occurs when light reflects off a rough surface and forms a blurry image or no image at all.
Do all bodies produce sound Class 8?
No, all the bodies cannot produce sound.
What are the applications of multiple reflection?
Multiple reflections are used in periscopes. Periscopes are used in submarines, war tanks and by solders in bunkers to see objects that are not visible directly. In a barber’s shop, we see the back of the head using multiple reflections of two mirrors.

How multiple images are formed?
Answer. The formation of multiple images: The images were formed when two mirrors are inclined at an angle and the object is located between the mirrors, numerous images are formed due to multiple reflections on the mirrors. The angle between the mirrors is responsible for the creation of multiple images.
