A tube closed at one end produces a fundamnetal note of frequency 480 Hz. If the same tube is kept open at both the ends, the fundamental frequency that can be excited is

A

240 Hz

B

120 Hz

C

960 Hz

D

720 Hz

Text Solution

Verified by Experts

The correct Answer is:
C
`f_("closed") = V/(4L) f_("open") V/(2L) = 2 [V/(4L)] = 2f _("closed")`
` :. f_("open") = 2 xx 480 = 960 ` Hz
