  • The Importance Of Photometry In The Laser Interferometer

    test. Interferometers are used to make very small measurements that cannot be achieved with any other method. An important application of interferometry is in the Laser Interferometer Gravitation wave Observatory(LIGO) which is used to detect gravitational waves predicted by Einstein.1.1 The LIGO interferometer is like the Michelson Interferometer as shown in…

  • Gravitational Waves

    However, this same percentage in the 2-meter stick will be twice as much as the stretch of the meter stick. Thus for the detection of gravitational waves, longer arms allow for more sensitive interferometers. There are other factors that could cause the arm lengths to fluctuate or appear to fluctuate, such as, thermal expansion, a non-stable laser source, or a poor vacuum. Anything that interferes with the detection of a gravitational waves signal is referred to as noise. If the laser…

    human health as they may have relation to cancer prevention. 2. Fourier transforms infrared spectroscopy (FTIR). FTIR is a method which is used to obtain an infrared spectrum of absorption, emission, photoconductivity of a solid, liquid or gas. The main use of this method is in organic and inorganic substances. It is also used to determine functional group in molecules. The basic components of an FTIR spectrometer are shown below: Figure 2: Basic components of an FTIR. (Source: Stuart,…
