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.)
b=237.7. and Td is in C. The vapor pressure is related to the relative humidity and vapor saturation pressure by. When the air is saturated the relative humidity is equal to 100%, and the temperature is equal to the dew point temperature, which allows us to solve for the dew point temperature.where. fourth parameter is often requested, the dew point temperature. This quantity can be calculated from the three measured parameters. The measured atmospheric pressure is the sum of two terms, the partial pressure of dry air (pa) and the partial pressure of water vapor (pw).
