You have a scope whose lens has na of 0.65. your illumination source lambda is 550 nm (ie white light). will you be able to clearly resolve (see) a bacterium 0.2 micron in diameter?

b. regulated is the actual answer to your question.

explanation:

mountains can affect the climate of nearby lands. in some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. much of airborne moisture falls as rain on the windward side of mountains.

explanation:

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
