Refractive index lab report
Home lab 5 refraction of light diamond is for the jeweler to measure its refractive index in an instrument known as a refractometer) as light enters a more optically dense material (eg from air into water or glass) spring 2009 ‐ home lab – week 5 ‐ refraction of light. Experiment 11 ~ reflection and refraction purpose: the purpose of this experiment is to investigate two of the basic laws of optics, namely the law. The refractive index the refractive index aim: the aim of this experiment is to find the refractive index of a glass prism in this experiment, the independent variable is the angle of incidence, and the dependent variable is the angle of refraction.
Th1 refractive indices of ethyl alcohol and water mixtures by taniiu nowaxowsd a thesis submitted to the gr4dujte school oj. Reflection and refraction equipment acrylic block set, plane-concave-convex universal mirror, cork board, cork board stand, pins, flashlight, protractor, ruler, mirror worksheet, rectangular block worksheet, equilateral prism. Experiment 4: refraction and interference with microwaves 3 figure 1 waves incident on an interface between index of refraction n 1 and n 2 we can see from figure 1 that: c n 1 (t 2 t 1) xsin(t) (6) ie, that in the time interval.
This video will run you through on how the refractive index of a glass block can be obtained through the use of a series of carefully placed optical pins. (please use headphones for better sound) (please use headphones for better sound. Refractive index n can also be defined for a particular material as the ratio of the speed of light in vacuum or free space to the velocity of light through the material (see equation 11) the refractive index also depends on the wavelength (colour) of the light ray. View notes - sample laboratory report from phy 11l at mapúa institute of technology abstract the index of refraction of a medium is a measure for how much the speed of light (or other waves such as.
A measuring refractive index with use of diffraction grating 1 required materials for conducting experiments you will need the following: laser pointer (alternatively laser level), diffraction grating with 200 to 500 lines per 1 mm. 1 lab 11: index of refraction (n) of air introduction in this experiment you will measure the index of refraction of air by comparing the optical path lengths of two columns of air of equal physical length but at different pressures. Conclusion the goal of this experiment was to verify snells law and the law of from phy 114 at arizona state university lab report 9 - reflection and refraction of light the goal of this experiment was to verify snell’s law and the law of reflection. Again it could be seen that a relation existed between wavelength and refractive index as the shortest wavelength had the largest refractive index and the longest wavelength had the smallest refractive index.

Pc1142 physics ii the prism spectrometer 1 objectives demonstrate the dispersion of light through a prism and the principle of a prism spec-trometer determine the index of refraction of a glass prism for various wavelengths determine the experimental values for the cauchy’s constants for the glass prism. Lab report (lab reports must be submitted to the physics lab at the end of your lab period the lab report may be submitted on a separate piece of paper or as a page in your notebook. Refraction of light the refractive index of air is approxi-mately unity, and all other materials have n 1 the refractive index is also a function of the wavelength of the light, therefore light rays of diﬀerent inclusion in your lab report • enter the pairs of values (sinr,sini) in the physicalab data window select scatter. O31 lab o3: snell's law and the index of refraction introduction the bending of a light ray as it passes from air to water is determined by snell's law.
Refractive index can be used to identify an unknown liquid compound, or it can be used as a means of measuring the purity of a liquid compound by comparing it to literature values the closer the refractive index is to the literature values, the purer the sample. Refraction is defined as the bending of light that takes place at a boundary between two materials having different indices of refraction due to a change in the speed of light as it passes from one medium to another. If you find that the index of refraction of the standard is consistently off by more than 00005 from the expected value report this to your instructor or the person in charge of calibrating the refractometer.
The science behind the water refraction experiment: refraction is the bending of light in this case, light traveled from the air, through the front of the glass jar, through the water, through the back of the glass jar, and then back through the air, before hitting the picture. Refractive index also called , index of refraction measure of the bending , of a ray of light when passing from one medium into another if i is the angle of incidence of a ray in vacuum (angle between the incoming ray and the perpendicular to the surface of a medium, called the normal), and r. Margaret wettergreen phy 2049l 04/03/2014 lab #11 – dispersion from a prism and index of refraction purpose: the purpose of this lab was to study the dispersion spectrum from a prism and to measure the index of refraction of the prism. Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another if i is the angle of incidence of a ray in vacuum (angle between the incoming ray and the perpendicular to the surface of a medium,.
