Physics Graded Assignment [Number 39]

1) How many images would you get for an object that is placed between two mirrors placed at an angle less than 90(degrees)?
When an object is placed between two mirrors that are placed at an angle which is lesser than 90degrees, there would be a minimum of 3 images formed. This is because light would reflect and bounce between the mirrors before it reaches your eye. Thus, the smaller the angle, the more images you see.

2) What happens to the images of this angle is it is bigger than 90(degrees)?
This is the exact opposite of having angles smaller than 90degrees. This means that the bigger the angle, the lesser images you see

3) How do mirrors produce funny images?
Different shapes of mirrors have different properties.
Convex = Convex mirrors are also curved mirrors, but the silvered surface bulges outward instead of inward.
Concave = Concave are spherical mirror.
When a person stands in front of a convex mirror, he/she would look thinner & slimmer .For a concave mirror, it would be the exact opposite.
