The sound waves pass through the door and will then go further from the space near the door making the sound hear outside the door also.
<u>Explanation:</u>
Waves can twist around corners in view of an impact called diffraction. The sum that a wave will twist around a corner as a result of diffraction is about equivalent to its frequency. So it is a lot simpler to see the bowing of the sound waves, since it is around a million times greater than the bowing of the light waves.
As the waves pass through the door, they bend and travel into the space near the door. Because they spread out into the space beyond the door, a person near the doorway can hear sounds from inside the room.
Answer:
h = 48.077 ft
Explanation:
given,
distance between two observer = 300 ft
angle of elevation to top pole = 16° and 20°
height of the flagpole = ?
now,
Let h be the height of the flagpole
Let x be the distance of the pole
now,
again applying
h = 48.077 ft
<span>A high-pitched sound results from "High Frequency waves"
In short, Your Answer would be: False
Hope this helps!</span>
