Document Summary
Object that is to be cloaked or made invisible. For most materials, the index of refraction n is greater than or equal to 1. There are negative index materials for which n is negative. The answer is no because of it is perfectly cloak. Friend sees the scene behind the cloaked person. Yes, because the velocity is always changing, so, it has be accelerating. Picture the atom like a small solar system. A spectrum is a list of the wavelengths or frequencies in a sample of radiation. For a solid object at a high enough temperature, the light form the object consists of a continuous band of the visible colours. A gas of atoms at a high enough temperature gives off light at discrete wavelengths. In quantum mechanics, atoms are described by quantum states. A quantum state gives the description of what the atom is doing. For a hydrogen atom, each state is labelled by an integer n. (n=1,2,3 )
