Abstract
In practical determination of the angular distribution of reflected light in the laboratory, the measurement of different materials was taken with the intention of determining their scattering properties. Glass prism set the center stage of the materials whose scattering properties were taken. The properties are known to define the scattering functions and the angular distributions based on the ratio of their elements which in the physics laboratory are seen to be the same as the degree of linear polarization of the scattered light (Adam et al., 2021). The LASER light of a certain wavelength was used and a scattering angle of 100 to 800 was covered.
The results were obtained showing patterns which can be described as to vary particularly as a function of scattering angles.
The results did not defer much from the theoretical assumptions that were made prior to the experiment. Among the determination made was that the angular distribution of these linear polarizations formed a curve and showed the highest point as it approaches the 900 mark. The phenomena led to conclusion that the morphology and the structural features of the elements of the prism played a role in the absorption and scattering of the light particles. The internal elements of the prism were able to scattered the incident light.
Introduction
The aim of the experiment was to determine how angular distribution of light can experimentally be carried out in the physics laboratory using the glass prism. It was questioning what happens when light when light that is travelling through a medium for instance a vacuum meets with the boundary of a certain medium that is having a different refractive index. There are several laws in physics that are incorporated when carrying out the experiment on the angular distribution of reflected light. One of the laws being applied is the Fresnel’s law which is defined as the ratio of the electric field of a reflected and a transmitted wave to the electric field of the incident wave. The law has the ability to describe the amplitudes of the waves and the phase difference between the waves (Starke & Schober, 2018). The underlying law in question can be practically used to differentiate the reflection and transmission of light when the light is incident on an interphase between different media.
The moment a plane wave constituting of electric fields is reflected on a regular surface, then some of the light particles of the light wave will be transmitted through the reflecting surface. According to Fresnel, the reflection and transmission coefficients are physically defined as
r= Er / Ei and t = Et / Ei
Where E is the electric field, t is the transmission coefficients and r represents the reflection coefficient. In the incidences where the electric fields are at 900 to the propagation direction of the waves, it implies that the electric fields can focus to any direction so long as the experiment is carried out in a two dimensional plane. In this case, the plane was taken to be in a two unit vector dimension as one marked to be the plane of incidence and the other to be at...
