We are about ¾ way through this “Hewitt” textbook in “Conceptual Physics”. Chapter 19 (Vibrations and Waves) explains that that there are two type waves shapes. These are transverse waves, and longitudinal waves. It seems to me that something either doesn’t add up, or is being left out. The book describes-
The longitudinal wave (actual point-to-point locomotion) is produce by a compression/rarefaction of whatever particulate medium the wave is transmitted in. This is a one-dimensional linear plane (movement-to-180o reverse or opposite movement). An in/out or push/pull action creates this wave. Is this correct?
The transverse wave (actual point-to-point locomotion) is produce by a Translational (transverse) movement from either high-to-low, side-to-side, right-to-left, or any other type movement-to-180o reverse or opposite movement on a transverse plane thru a medium that is transmitting the wave. Is this correct?
Question #1-
Is there a possibility that there is such a thing a Spherical Wave Motion?
What causes me to ask this is, all matter that we are aware of here on earth, is made of some sort of orbital/spherical atomic particle. Is this correct? If so, the expanding then collapsing of the electronic orbits would produce a multi-dimensional (spherical) expanding/collapsing wave-form. If this is true, why is it not mention more commonly?
Question #2-
Is there a possibility that there is such a thing a Rotational Wave Motion?
What causes me to ask this is, the example in the book show the shaking of one end of a rope while the other end is attached to a fixed point to demonstrate a transverse wave. This wave is produced only on a one-dimensional axis that appears to be able to be produced in any of the 2pie vectors. If the rope were to be spun in an orbital circle (like a jump rope normally is), wouldn’t this produce a wave form that at any visual point of view, look like both a frequency modulated and a amplitude modulated wave but is originated in a totally different manner than all others?
I have posted question before on the class (internet forum) web page, just to either not get no response, or get one that reflects a “who cares attitude”.
Anyone have a thought about this?
