In a plane mirror, you can determine the images formed in a certain angle by using the formula:
[tex]n \: = (360 /θ) \: - 1[/tex]
whereas:
n = number of images formed
θ = given angle
Solution:
[tex]n \: = (360 /180°) \: - 1[/tex]
[tex]n \: = 2 \: - \: 1[/tex]
[tex]n \: = \: 1[/tex]
Therefore, the number of image/s formed in 180° angle will be 1 image.
