Bob has two tubes that both support (or hold) standing sound waves with the same frequency. Tube A has two open ends, and Tube B has one open end and one closed end. The value of the fundamental frequency for both tubes is the same.(a) How many wavelengths long is Tube A for the fundamental mode (or frequency)? ---Select---0.250.51.02.0(b) How many (of the same) wavelengths long is Tube B for the fundamental mode (or frequency)? ---Select---0.250.51.02.0(c) If the length of Tube A is 0.83 m, how long is Tube B?md) A standing sound wave with frequency 213 Hz is set up in a tube that is open at both ends. Take the speed of sound in air to be 347 m/s. If this standing wave has the fundamental frequency for this tube, meaning that the standing wave is a sound wave with the longest possible wavelength for this tube, what is the length of the tube?HINT: Draw a picture of this standing wave and identify how long the tube is in terms of number, or fraction, of wavelengths. m
