Below is a plot of the data taken with the hene laser light injected into the michelson interferometer mirror 1 (m1) inside the michelson interferometer is being translated at a constant speed by a motor these data are used to find the speed of m1 which will be used in the sodium light section - to easily. The purpose of this experiment is to give you some practice in assembling, aligning and using a michelson interferometer to measure the index of refraction of air the principle of the michelson interferometer is shown in fig 1 light from a laser is incident on a beam splitter (bs) which consists of a glass plate with a partially. Physics 263 experiment 8 michelson interferometer 1 introduction the michelson interferometer uses light interference to measure distances in units of the wavelength of light from a particular source it was developed by albert michelson and used, in 1893, to measure the standard meter in units of the wavelength of the. Optical michelson interferometer 1 optical path a diagram of the interferometer is in figure 51 diffuse light from a monochro- matic source illuminates a beamsplitter your lab report when the pressure is increased, do new rings appear to come out of the center or do they move into the center and disappear why. Experiment 4 the michelson interferometer 1 introduction there are, in general , a number of types of optical instruments that produce optical interference these instruments are grouped under the generic name of interferometers the michelson interferometer causes interference by splitting a beam of light into two parts.
The light sources used in this experiment (na lamp, hg lamp and incandescent lamp) can become quite hot take care not to touch the actual lamp housings when the lamps are on 2 to avoid back and neck strain, when looking into the interferometer choose a low chair or stool so your eyes are approximately level with. This is an example of a well-written formal report from the phys 332 lab particularly pertinent features are called out in the based on a report by dan sutton, jon denlinger and william leaf, physics 450 purdue university, march 4 , 1982 michelson interferometer the next section describes the calibration and use of. Michelson interferometer is a widely used instrument for measuring wavelength of light, refractive index of transparent materials etc the interferometer model no ho-ed-int-06 is designed and constructed in modular fashion students can assemble the interferometer out of individual modules by fixing.
Experiment 3 1 the michelson interferometer and the he-ne laser physics 2150 experiment no 3 university of colorado introduction in the experiment, two different types of measurements will be made with a michelson interferometer the first will be a direct measurement of the wavelength of the 6328-angstrom. I assume that by blocking an arm you mean that you prevent light from going through that arm the michelson interferometer causes interference between two parts of the incident wave, that has been divided by the beam splitter if you prevent light to go through one arm of the interferometer, for instance by.
This setup is named) which in 1887 resulted in the michelson–morley experiment (performed together with edward w morley) the basic michelson interferometer setup uses any kind of beam splitter to divide one beam of light into two beams, each (to be answered in a separate part of the report) 1 please calculate. In this experiment you will assemble a michelson interferometer that operates simultaneously with a red ( = 6328 å) hene laser and a green ( = 543 nm further precision is being withheld intentionally) so called grene laser the grene laser uses a hene discharge tube, but the optical resonator forces lasing at the. The objective of this experiment is to observe the interference of light by combining coherent monochromatic light beams using a michelson interferometer you will determine the wavelength of the light source from your notebook submit your answers on the web site safety caution: take extreme care when.
Michelson to accurately detect aether flow) to try and detect the relative motion of light a diagram of the microwave interferometer is shown below: lab in a box – microwave interferometer answers q: move the movable mirror backwards and forwards along the apparatus you should notice the voltage. 228, 012012 (2010) 13 the virgo collaboration, “advanced virgo technical design report”, vir-0128a-12 (2012) m w regehr, f j raab, and s e whitcomb, “demonstration of a power-recycled michelson interferometer the interferometer by squeezed light injection, was carried out in a subsequent experiment and. A detailed theory of the michelson interferometer is given in halliday and proceedings of the american academy of arts and two laboratory reports are required now you should not report a measurement in physics without some kind of full wave rectification lab report week 11–12: mar michelson.
Finally, we report the observation of white light fringes that occur keywords: optics michelson interferometer mercury spectrum white light fringes this experiment) this data represents the third at- tempt at procuring accurate data the first two sets were deemed invalid because of human error, either. Using michelson interferometer, one can determine the wavelength of light from a monochromatic sourceit can also be used to calculate the refractive index of a thin film. How to align the laser and optics, some information on making the measurement.
