Best Answer: Coarse adjustment is used to focus the image on the microscope under low or medium power by using larger motions of the lens. Fine adjustment is used to focus the image on the microscope of only high power by using very tiny motions of the lens.
If you are interested in a simpler calculation that gives an approximation of dew point temperature if you know the observed temperature and relative humidity, the following formula was proposed in a 2005 article by Mark G. Lawrence in the Bulletin of the American Meteorological Society: Td = T - ((100 - RH)/5.)
Step 2: Vapor Pressure. Relative humidity can be expressed as a ratio of the saturation vapor pressure at the dew point temperature to the saturation vapor pressure at the air temperature. This is expressed by the formula RH = 100*(e/e s).or example, a dew point temperature below freezing indicates very dry air. On the other hand, a dew point temperature of 70 degrees F would occur on a humid, muggy day. Below you will find the step by step process that will teach you how to calculate dew point.
