Answer:
B)Diffraction
Explanation:
The concept of diffraction in the field of physics is defined as the deflection of a wave when it crosses an opening or hits the edge of an opaque element. Diffraction is a phenomenon that involves all waves: electromagnetic, radio, sound, etc., and it is possible to predict their behavior using different mathematical approaches. There is a method of analysis called the Huygens principle, which allows us to understand diffraction as a wavefront that is seen as a series of emitters capable of redirecting the wave when it oscillates and thus promotes propagation. Although the waves produced by the oscillators are spherical, their interference causes a flat wave that moves in the same direction as the initial one.
Answer:
1234285.7 m or 1234.3 km
Explanation:
Let the distance be , the time taken by P waves be
and the time taken by the S waves be
.
For the P waves,
For the S waves,
Equating the ,
Divide both sides of the equation by 500 to reduce the terms.
Since S waves arrive 2 minutes (= 120 seconds) after P waves,
Substitute this in the equation of the distance.
Substitute this in the equation for involving
.
