Extending Conditional Formatting in Google Sheets Using Dynamic Date Calls. Google Sheets, the spreadsheet tool that's part of the Google Apps productivity suite, lets users format cells based on certain conditions, including the date contained in a cell and how far away that date is from the present.
The Geiger counter, is an instrument used for measuring ionizing radiation used widely in such applications as radiation dosimetry, radiological protection, experimental physics and the nuclear industry.eiger counters are widely used to detect gamma radiation, and for this the windowless tube is used. However, efficiency is generally low due to the poor interaction of gamma rays compared with alpha and beta particles.
A spectrometer is used in spectroscopy for producing spectral lines and measuring their wavelengths and intensities.Spectrometer is a term that is applied to instruments that operate over a very wide range of wavelengths, from gamma rays and X-rays into the far infrared.If the instrument is designed to measure the spectrum in absolute units rather than relative units, then it is typically called a spectrophotometer.pectrometers are used in many fields. For example, they are used in astronomy to analyze the radiation from astronomical objects and deduce chemical composition. The spectrometer uses a prism or a grating to spread the light from a distant object into a spectrum.
