Question
A/an ____ is the best reflector of light.
- Glass
- Mirror
- Plastic
- Wood
Hint:
The best reflectors are smooth.
The correct answer is: Mirror
A flat mirror has one polished surface and one glossy surface and reflects light so that all reflected rays travel in the same direction, causing specular reflection of light. Mirrors can reflect 95% of the light that falls on them. It usually has a coating of silver or aluminum.

An incident ray goes along the reflecting surface. The angle of reflection is ____ degrees.
When the angle along the reflecting surface , the incident ray is perpendicular to the reflecting surface. We know by the first law of reflection that angle of incidence is equal to angle of reflection . Here, the angle of incidence is 90 degrees so the angle of reflection will also be 90 degrees.
