A Circle is a two-dimensional figure whereas, a Sphere is a three-dimensional object. A circle has all points at the same distance from its centre along a plane, whereas in a sphere all the points are equidistant from the centre at any of the axes.
Yes I can!
Sound waves are always transverse. Meaning they look up and down like an actual wave. Sound waves must contain what we call a medium, a medium is what carries the wave. Sound waves a partially carried by air. The distance from one crest (the top of the save) to another crest is called wavelength. Wavelength can be from crest to crest AND trough to trough (The bottom of the wave). The amplitude is from the crest (or trough) to the rest position.
<em>I hope this helps! Please let me know if you have anymore wave questions, for that is the thing I know best!</em>
Hello,
To have a good behaviour, you must be serious, calm and nice :)
