A string is tied at both ends, and a standing wave is established. The length of the string is 2 m, and it vibrates in the fundamental mode ( n = 1).1) If the speed of waves on the string is 60 m/s, calculate the wavelength of the waves. (Express your answer as an integer.)2) If the speed of waves on the string is 60 m/s, calculate the frequency of the waves. (Express your answer to two significant figures.)
