Earthquakes generate compressional waves (p-waves) and shear waves (s-waves). Compared to the speed of shear waves in a given earth material, the speed of compressional waves is the fastest.
Because of this the compressional waves are the first waves to arrive on a complete record of ground shaking. They are also called P waves, which derives from this fact - P is an abbreviation for primary, first wave to arrive.<span>They typically travel at speeds between ~1 and ~14 km/sec.</span>
Answer:
Rays of light emanate from a real image, but only appear to do so from a virtual image.
Explanation:
- The real images are inverted to the object and rays of light are emitted from the virtual object tends to do so and this image is always bigger than the object.
- Thus a real image occurs where the rays of light converge and a virtual Image occurs when the rays of light diverge and a virtual image can't be projected to a screen as compared to a real image.
If you have choices, it would be really helpful if you'd include them with your question, but I'd say
