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.)
One can calculate the absolute humidity (AH) from the relative humidity (r) using three equations: (1) the equation for mixing ratio, (2) an equation for relative humidity expressed in terms of mixing ratio, and (3) the Clausius-Clapeyron equation, which relates saturation vapor pressure to temperature.bsolu â¦ te humidity then is the total amount of water vapor contained in the air regardless of temperature. Relative humidity is the ratio to the amount of water the air is able to hold at a given temperature compared to the amount of water vapor it currently has (its absolute humidity).
