Different types of mirrors
Periscope (plane mirror)
Blind corner mirror (curved mirror)
Satellite dish (curved surface)
Curved surface
Law of reflection
The angle of incidence (i) is equal to the angle of reflection (r).
~~at the point of incidence (P), the incident ray, the normal, and the reflected ray all lie in the same plane.
Application of mirrors
Periscope (plane mirror)
~ look over an obstacle such as a high wall
Blind corner mirror (curved mirror)
~ allow shopkeepers to look out for shoplifters
~ help drivers to see around blind corners before making a turn
Satellite dish (curved surface)
~ receiving satellite dish, it has a radio receiver located at the focus of the parabola
~ transmitting satellite dish, it works in the exact opposite way of the receiver
Curved surface
~ solar heating and generating solar electricity
In the mirror maze, we were surrounded by countless plane mirrors! Once inside, we had to find our way through the maze, to locate the exit. As easy at it seems, it was quite of a challenge for some of us because wouldn't it be nerve-wrecking if you kept banging into the same mirrors, stuck and unable to find your way to the exit? A "strategy" I adopted was keeping my hand out so if it gets reflected, it means there's a mirror there and if it doesn't, it's a clear path! This strategy sure helped me from banging into the mirrors:)
