Normal line
An imaginary line is drawn perpendicular to the surface of a mirror or any surface

Reflection light reflected normal same incidence
When Lights hits a mirror, the angle at which it hits is the Incidence as the angle at which it is Reflected. Scientists called this the Law of Reflection. Incorrect science terms, the Reflection Law states that the angle of Normal is equal to the angle of Same when measured from the Reflection.

Research Task:
- What is a periscope? Is an optical instrument that uses a system of prisms, Lenses or mirrors to reflect images through a tube.
- How does it work? Light from a distant object strikes the top mirror and is then reflected at an angle of 90 degrees down the periscope tube.
- Draw and label a periscope?
