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.)
Rating Newest Oldest. Best Answer: Dew point is the temperature at which relative humidity reaches 100%. At this point, the air is so full of moisture that it cannot hold any more water.Thus, dew forms on anything that is at the dew point or lower.Often dew forms at night, because the air cools at night and can easily reach the dew point. The closer the dew point is to the actual temperature, the more humid it is.ating Newest Oldest. Best Answer: Dew point is the temperature at which relative humidity reaches 100%.
