An object is placed between two mirrors which are inclined at an angle of 120° and facing each other. Determine the number of images observed in the two mirrors

Answer Details

When two mirrors are inclined at an angle, the number of images formed is given by the formula n = 360°/θ - 1, where n is the number of images and θ is the angle between the mirrors. In this case, the angle between the two mirrors is 120°. Substituting in the formula we have, n = 360°/120° - 1 = 3 - 1 = 2. Therefore, two images will be observed in the two mirrors.
