A teacher asks 4 students to find the speed of sound using resonance column apparatus. The set of apparatus used by each of student was different. The frequency of tuning fork used was known precisely. He wants the error in speed of sound to be within 1%. Which of the student(s) did the experiment correctly. Their results are tabulated below. Student Frequency 1st resonance 2nd resonance (A) 50.0 cm 476 Hz 17.0 cm 340 Hz 25.2 cm (B) 76.0 cm 544 Hz 15.6 cm (C) 46.0 cm 510 Hz 16.0 cm 48.2 cm
