Light is atransverse wave consisting of energy in the form of electric and magnetic fields. The directions vibrate in right angles.
The speed of light is symbol c on the reference table. The speed of light in a vacuum is c = 3.00 x 108 m/s. The electromagnetic spectrum is:
Rays indicate the direction of wavefront motion.
-Circular wavefronts = radical lines
-Plane wavefronts = parallel lines
Reflection is the change in direction of a wave front at an interface between two different media so that the wave front returns to the medium from which it originated.
Law of Reflection
Angle Of Incidence (qi) = Angle Of Reflection (qr)
qi = qr
Types of Reflection
Specular Reflection
-Smooth Surfaces
-Usually Produces and Image of The Source
-Mirrors
Diffuse Reflection
-Rough Surfaces
-Scattered Light
-Each Individual Ray Follows The Rule of Reflection
