WebDouble slit interference. Say you have a laser pointer. A laser is basically just a bunch of light waves that all have the same wavelength and are all lined up with one another. Suppose … WebP waves are like the lightning, and S waves are like the thunder. The P waves travel faster and shake the ground where you are first. Then the S waves follow and shake the ground also. If you are close to the earthquake, the P and S wave will come one right after the other, but if you are far away, there will be more time between the two.

WebSeismographs - Keeping Track of Earthquakes. Throw a rock into a pond or lake and watch the waves rippling out in all directions from the point of impact. Just as this impact sets waves in motion on a quiet pond, so an earthquake generates seismic waves that radiate out through the Earth. 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 …
WebOct 1, 2024 · A tsunami is a series of extremely long waves caused by a large and sudden displacement of the ocean, usually the result of an earthquake below or near the ocean floor. This force creates waves that radiate outward in all directions away from their source, sometimes crossing entire ocean basins. Unlike wind-driven waves, which only travel ...
