How do spectrophotometers work? The basic function of a spectrometer is to take in light, break it into its spectral components, digitize the signal as a function of wavelength, and read it out and display it through a computer. In most spectrometers, the divergent light is then collimated by a concave mirror and directed onto […]

Does a dryer use a lot of electricity? Electric dryers span a wide range of wattages, from about 2,000 to 6,000 watts. That translates to about 2 to 6 kilowatt-hours of electricity. Based on the national average rate of 12 cents per kilowatt-hour, each hour of electric drying will cost somewhere between 24 and 72 […]
