The human body creates and responds to a variety of waves. Select all of the true statements. Correct the false statements. a. The vocal cords produce sound waves by vibrating air molecules perpendicularly to the direction of travel. b. The sound waves produced when you clap your hands are examples of surface waves. c. The ear detects pressure waves that vibrate the air parallel to the direction the wave travels. d. An ocean swimmer bobs up and down and side to side because surface waves are a combination of both longitudinal and transverse waves. e.

Stretched string

A stretched string is a wire which is made up of any metal that must have a larger length compared to its thickness. The ends of the wire are fixed, and when they oscillate or are plucked, it produces two reflected transverse waves of the same frequency and same amplitude. The waves or pulses are traveling in alternate directions and superimpose with one another. This waveform is named standing or stationary waves.
