The lens is transparent piece of glass or plastic which has a curved surface. There are two types of lenses: converging (convex lens) and diverging (concave lens). The principle behind the lens is the refraction of light.

Descriptive research answers questions relating to “what,” describing the nature of demographics under study. It doesn’t focus on the “why” of the research subject. More specifically, it describes the attributes of the variables in the study without changing them. Descriptive research is genera...

Alright, now that we're on the other side of the looking glass, we can take a closer look at these thin lenses. I mentioned that a thin lens is one with minimal width compared to the height and circumference of the lens, but how exactly do we measure this? Lenses are measured in di...
Types of Antenna Abstract An optical telescope uses either a mirror or a lens to collect light. The light is then brought to a focus and magnified by an eyepiece. An antenna in some respects can be likened to an optical telescopes lens or mirror, as the antenna collects the radio signals...

2020, Results in Physics Citation Excerpt : Besides, the studies about the AAF beams exerting on a Mie or Rayleigh particle have aroused much attention [12,13]. Very recently, many different types of partially coherent beams were proposed to improve the performance of the optical trapping [23–...
