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.)
The dew point temperature is that temperature where, by cooling of the air at constant pressure, the formation of dew begins. When the temperature and the dewpoint temperature are equal, the relative humidity is 100%. In a weather forecast, it's another way of describing the amount of moisture in the air; the higher the dew point, the greater the water vapor content in the air. Related Questions.
