Which phenomenon occurs when a wave encounters a non-transmitting barrier?

When a wave encounters a non-reflective barrier, diffraction of the wave energy occurs.

Explanation:

Waves are movements caused in systems, which are caused by disturbances that occur on the medium. A wave does not have the ability to carry matter, it can only carry energy.

Whatever the type of wave, it is subject to the phenomena of reflection, refraction and diffraction.

The phenomenon called diffraction is nothing more than the deviation or scattering suffered by the wave when it circumvents or overcomes obstacles placed in its path, these obstacles represent a barrier not reflecting the wave. We can say that this phenomenon happens to all types of waves and is easily noticeable when it comes to sound waves. An example of sound diffraction is when we are listening to music being played on the other side of a wall.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
