An air column in a pipe which is closed at one end, will be in response with the vibrating body of frequency 83 Hz. Then the length of the air column is

An air column in a pipe, which is closed at one end, will be in resonance with a vibrating body of frequency 166 Hz , if the length of the air column is

An air column in a pipe which is closed at one end will be in resonance with a vibrating tuning fork of frequency 264 Hz if the length of the air column in cm is (Speed of sound in air = 340 m/s)

An air column in a pipe, which is closed at one end, will be in resonance with a tuning fork of frequency 200 Hz, if the length of the air column is [ velocity of sound in air = 320 m/s]

An air column in a pipe, which is closed at one end. will be in resonance with a vibrating tuning fork of frequency 264 Hz if the length of the column in cm is-
