Solution for On-Line Homework 26 Waves I Solution to On-Line Homework Problem 26.1() Problem: What best describes the motion of the particles in the medium for a transverse wave? Select One of the Following: (a) In a transverse wave the particles in the medium move back and forth along the direction the wave is traveling. (b) In a transverse wave the particles in the medium move consistently in the direction the wave is traveling. (c-Answer) In a transverse wave the particles in the medium move back and forth perpendicular to the direction the wave is traveling. (d) In a transverse wave the particles in the medium move consistently in the direction perdendicular the wave is traveling, traveling outward. Solution A transverse wave has a displacement which is perpendic- ular to the direction of propagation (i.e. shaking the free end of a string that is tied o± on the opposing end will

Unformatted text preview: generate a transverse wave). A longitudinal wave is has 1 a displacement in the same direction of propagation (i.e. compressing the end of a coil spring can generate longitu-dinal waves). Total Points for Problem: 2 Points Solution to On-Line Homework Problem 26.2() Problem: What is the eFect on the speed of wave propagation as the tension in a string is increased, if no other quantities change? Select One of the ┬▒ollowing: (a) The speed is unchanged, since it is determined by whatever causes the wave. (b) The speed decreases. (c-Answer) The speed increases. (d) There is no way to tell what will happen to the speed. Solution As the tension in a string is increased, the speed of wave propagation down the string will increase, and if the tension in the string is decreased, the wave speed will decrease.
