In a common laboratory experiment on standing waves, the waves are produced in a stretched string by an electrical vibrator that oscillates at 60 Hz (Fig. 13.28). The string runs over a pulley, and a hanger is suspended from the end. The tension in the string is varied by adding weights to the hanger. If the active length of the string (the part that vibrates) is 1.5 m and this length of the string has a mass of 0.10 g, what masses must be suspended to produce the first four harmonics in that length?
Answer to relevant QuestionsA student uses a 2.00-m-long steel string with a diameter of 0.90 mm for a standing wave experiment. The tension on the string is tweaked so that the second harmonic of this string vibrates at 25.0 Hz. (a) Calculate the ...A 2.0-kg mass resting on a horizontal frictionless surface is connected to a fixed spring. The mass is displaced 16 cm from its equilibrium position and released. At t = 0.50s, the mass is 8.0 cm from its equilibrium ...Is it possible for an open organ pipe and a closed organ pipe, each of the same length, to produce notes of the same frequency? Justify your answer. What is the speed of sound in air at (a) 10oC and (b) 20oC? A bat moving at 15.0 m/s emits a high-frequency sound as it approaches a wall that is 25.0 m away. Assuming that the bat continues straight toward the wall, how far away is it when it receives the echo? (Assume the air ...
