How does the angle between two mirrors affect the number of images you can see?

   Students in Teacher Chris’s EP M2 Science class investigated the properties of light reflection using two plane mirrors. Students joined the mirrors together to form an adjustable angle and placed a small object, such as a coin, between them. Using a protractor, they tested different angles of 120°, 90°, and 60°, counting and recording the number of images formed at each angle. They also explored what happened when the mirrors were closed to approximately 45°. Through this hands-on investigation, students discovered how light can reflect multiple times between two mirrors, producing multiple images, and explored how changing the angle between the mirrors affects the number of images they see. This activity helped strengthen their understanding of multiple reflection and the behavior of light.
