How many images are formed when two plain mirriors are placed at 150 degree angle?
When two plain mirrors are placed at a 150-degree angle, multiple images are formed. The number of images formed can be calculated using the formula: ( \text{Number of images} = \frac{360}{\text{angle between the mirrors}} - 1 ). In this case, with a 150-degree angle, the calculation would be ( \frac{360}{150} - 1 = 2 ) images are formed.
Why are multiple images formed when two mirrors are placed at right angles to each other?
With two mirrors at right angles you will have 3 (360/90 - 1) images of an object. Two of these are primary and the third is secondary. Some light rays from the object bounce of each of the mirrors to your eye to form the two primary images. But there are other rays that bounce off a mirror onto the second mirror before they get to you. This produced the secondary image.
When two plane mirrors are placed at an angle of 60 degrees to each other the images formed are?
Virtual images.
What are planes of symmetry?
They are 'mirror images'
Which type of imagery is easiest to form?
People generally have an easier time forming visual images than images of other sensory experiences.
