1 waves the wave model A traveling wave is an organized disturbance propagating at a well-defined wave speed v . In transverse waves the particles of the medium move perpendicular to the direction of wave propagation. In longitudinal waves the particles of the medium move parallel to the direction of wave propagation. A wave transfers energy , but no material or substance is transferred outward from the source. demo

2 three types of waves Three types of waves: Mechanical waves travel through a material medium such as water or air. Electromagnetic waves require no material medium and can travel through vacuum. Matter waves describe the wave-like characteristics of atomic-level particles. For mechanical waves, the speed of the wave is a property of the medium. Speed does not depend on the size or shape of the wave. The displacement D of a wave is a function of both position (where) and time (when).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
