1.	Calculate the number of images formed by two plane mirrors placed at an angle of 30 to each other.State any two applications of multiple reflection.
Answer» Answer: 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 reflectionsof two mirrors. Explanation: Multiple reflections are seismic events that have undergone more than one reflection between source and detector. As a seismic wave travels through the earth, it is split into a reflected and a transmitted wave at each acoustic discontinuity.
