WebNov 22, 2024 · The presence of the U wave depends on the heart rate. It is rarely registered at heart rates above 95 bpm, while it is better observed at heart rates less than 65 bpm. … WebA wave is a change (a variation) that travels through a substance (or medium). You can often see the change, such as the increased height of a traveling ocean, but what is important to understand is that the medium itself does not travel with the wave. Ripples in a pond are good examples of waves.
WebApr 1, 2024 · Since incident wave and its reflected part in opposite phase superimpose on each other. So correct answer will be. Option B. Explanation: Here we know that the wave reflection is done by rigid boundary. So when wave is reflected by the boundary then its phase is reversed by 180 degree. so the reflected wave is in reverse phase from the … WebThere are two explanations. (1) In the film shots you can see the astronauts rotating the flagpole as they push it into the ground. This rotation causes the flag to wave backwards and forwards.
