Physics of light

The limits of current micro-scale technology is approaching rapidly. As the technology is going toward nano-scale devices, physical phenomena involved are fundamentally different from micro-scale ones. Principles in classical physics are no longer powerful enough to explicate the phenomena involved in nano-scale devices. At this stage, quantum mechanic sheds some light on those topics which cannot be described by classical physics. The primary focus of this research work is the development of an analysis technique for understanding the behavior of strongly perturbed harmonic oscillators.

The purpose of this thesis is to study and synthesize BiMO materials (M = V,Ti,Sn) by microwaveassisted chemical method, hydrothermal method, sol-gel method and evaluate their physical properties. The synthesized materials (Bi2Sn2O7 and Bi2Ti2O7) were investigated the photocatalytic activity in the decomposition of RhotaminB (RhB) under visible light.

Infrared radiation is a type of electronmagnetic radiation (a wave with electricity) . The wave is longer than light which humans can see and shorter than microwaves. • The name means "below red". The word "Infrared" is from the Latin infra ("below") and red, which has the longest wave for light.

Interference and diffraction of light are arguments for wave charactiristics of light. We know that there are two types of wave processes: transverse & longitutional waves →to what are light waves belong ? Study of polarization of light makes clear that This conclusion is in according to the concept that light waves are electromagnetic waves with a definte band of frequencies. Recall that electromagnetic waves are transervse waves in which e-vectors & m-vectors oscillate in such follwing directions...
