Question on: JAMB Physics - 1990
In a resonance tube experiment, the effective length of the air column for the first resonance is 20cm when set into vibration by a tuning fork of frequency 480Hz. Neglecting and effect, the velocity of sound in air is
A
96ms-1
B
255ms-1
C
340ms-1
D
384ms-1
Ask EduPadi AI for a detailed answer
Correct Option: D
(\lambda) = 4(L + C) ; where C = o
(\lambda) = 4 x 20 = 80cm
V = (\lambda)F
= 80 x 10-2 x 480 = 384ms-1
