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.)
Dew point is a temperature at which dew droplets would form. So if the dew point is 75, and the air temperature is 75, youâd see fog or dew. But look what happens with relative humidity. Assume a constant dew point of 72: when the air temperature is 90, relative humidity is just 55 percent.âThat seems almost comfortable, but you walk out here and weâre sweating,â Shaffer said. If itâs 100 and the dew point is 72, relative humidity would be 40 percent.o if the dew point is 75, and the air temperature is 75, youâd see fog or dew. But look what happens with relative humidity.
