Physics Graded Assignment (REG NO. 18)




1) How many images would you get for an object that is placed between two mirrors placed at an angle less than 90(degrees)?

For an image place at an angle of 90 degrees, 3 images are produced. For an image place at an angle lesser than 90 degrees, more than 3 images are produced. For example, at 60 degrees, 5 images are produced. At 45 degrees, 7 images are produced.

2) What happens to the images if the angle is bigger than 90(degrees)?

The images produced will have different views. For example, if two mirrors are placed at 120 degrees, 2 images are produced. Which mean, the greater the angles, the lesser the images are formed.

3) How do mirrors produce funny images?

Through different shapes of mirrors. Different shapes of mirrors have different geometrical properties. If you stand in front of a concave mirror, the image produced will be stretched and shows a fat image of you. If you stand in front of a convex mirror, the image produced is thinner and shows a slimmer and taller image of you.
