For an electron that interacts with visible light, which visible photon would give the most accurate (lowest error) measurement of momentum (or speed)? blue
yellow
green
orange
violet

violet

Explanation:

When an electron interacts with visible light, energy is transferred from the photon to the electron.

The most accurate (lowest error) measurement of momentum (or speed) of an electron is obtained using a photon of high energy and low wavelength.

Violet light which lies at the high energy end of spectrum is most suitable.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
