Wind shear is the ingredient that turns an ordinary thunderstorm into a monster. Study the mechanisms that underlie this transformation. Then evaluate the crucial difference between a severe weather watch versus a warning, and put yourself in the shoes of a forecaster calling the shots.

This program covers the important topic of superposition and interference of waves in Physics. We begin by discussing two or more waves can interact by adding the amplitudes of the waves together. This is known as superposition of waves. The entire lesson is taught by working example problems beginning with the easier ones and gradually progressing to the harder problems. Emphasis is placed on giving students confidence in their skills by gradual...
