The line spectrun of any element has lines corresponding to definite wavelengths. Lines are obtained as a result of electronic trasnisions between the energy levels. Hence , the electrons in these levels have fiexed energy i.e. quatizied valeus.

The DroughtThen it didn’t rain–by midsummer, it was clear that the continental U.S. was in serious drought, including California, whose beekeepers supply nearly half the bees for almond pollination. The only ways that we kept our colonies strong was to either feed expensive pollen ...
known as the Arctic Oscillation (AO). When atmospheric pressure over the Arctic is low and pressure over the mid-latitudes is high, theAOis said to be in its positive phase, which supports a tight and fast-moving zonal, west-to-east airflow - the Polar Vortex - as the diagram below ...
