Question

Compare radial probability curve of
(i) 1S and 2S
(ii) 2S and 2p

Answer 1

Explanation:

Galileo Galilei is often claimed to be the inventor of the thermometer. However the instrument he invented could not strictly be called a thermometer: to be a thermometer an instrument must measure temperature differences; Galileo’s instrument did not do this, but merely indicated temperature differences. His instrument therefore, should rightly be called a thermoscope.
