A sinusoidal wave of frequency f is traveling along a stretched string. The string is brought to rest, and a second traveling wave of frequency 2f is established on the string. (i) What is the wave speed of the second wave? a. twice that of the first wave b. half that of the first wave c. the same as that of the first wave d. impossible to determine (ii) describe the wavelength of the second wave. a. twice that of the first wave b. half that of the first wave c. the same as that of the first wave d. impossible to determine (iii) describe the amplitude of the second wave. a. twice that of the first wave b. half that of the first wave c. the same as that of the first wave d. impossible to determine
