Study Notes

Reflection of Electromagnetic Wave

Reflection of an electromagnetic wave occurs when the wave bounces back from a surface, without changing its frequency or wavelength, but with a change in direction.

Normal in Reflection

The normal is a line perpendicular to the surface at the point of incidence, where the incident wave meets the surface.

Laws of Reflection

The incident ray and the reflected ray lie in the same plane, which is normal to the surface.
The angle of incidence is equal to the angle of reflection.

Incident Angle of 0 Degrees

If the incident angle is 0 degrees, the incident ray and reflected ray are perpendicular to the surface, and the reflection is symmetric.

Types of Reflectors

The laws of reflection are employed in flat mirrors, curved mirrors, and other reflective surfaces.
