What is the minimum vertical length of the mirror if the man is to be able to see the whole of his himself.Indicate its position accurately by a diagram.

What happen if the top of the mirror is tilted to an angle of 30 degree towards the man?

Answer 1

for the man to be able to see his entire imagine in a mirror, the minimum length of the mirror would be half of the height of the man, so 1 meter. To deal with what would happen if the mirror were not vertical, you would need to know the distance from the man to the mirror.
