Reflection and Mirrors
... raise your right hand, your image raises its left hand. However, up and down are not reversed. The image you see in a plane mirror is not simply flipped around. Instead, you see an object as if you were viewing it from just behind the surface of the mirror. ...

Reflection
... • Spherical aberration can be avoided by using a parabolic reflector; which are only a little more difficult/expensive to make. • Typically used in Telescopes, Camera lenses Lab equipment, shaving/make-up Mirrors, and this solar fire-lighter for campers! • Mirrors are preferred to lenses in many ...

... The equation (6) is Lambert’s cosine law called also „cosine emission law”. This law is valid only for socalled point light sources that is sources whose dimensions are small compared to the distance from a light source to an observer. Lambert’s law can be used for all light sources whose diameter i ...

Chapter 23: Electromagnetic waves What will we learn in this chapter?
... The wave is transverse, i.e., both E and B are perpendicular to the direction of propagation and to each other. There is a definite ratio between the magnitudes: E = cB The wave travels in vacuum with a constant speed c. The wave does not need a medium to propagate. The fields ...

One of them is called the ordinary beam which is characterized by an ordinary refractive index, and the other is called extraordinary and is characterized by an extraordinary refractive index. For each ...
