Direction: A plane mirror is a mirror with a flat reflective surface.
An incident ray is a ray of light that strikes a surface. The reflected ray corresponding to a given incident ray, is the ray that represents the light reflected by the surface. In figure, m and n are two plane mirrors perpendicular to each other.
Q. If BO = 3 cm, AB = 5 cm then, AO =
  • a)
    3 cm
  • b)
    2 cm
  • c)
    4 cm
  • d)
    6 cm
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
Direction: A plane mirror is a mirror with a flat reflective surface....
M and n are two plane mirrors perpendicular to each other.
So, AO is perpendicular to BO.
Thus, triangle AOB is a right-angled triangle.
OA2 + OB2 = AB2
OA2 + 32 = 52OA2 + 9 = 25
OA2 = 25 – 9 = 16
OA = 4 cm
