If the velocity of sound in air is 350 m/s. Then the fundamental frequency of an open organ pipe of length 50 cm, will be

If the length of a closed organ pipe is lm and velocity of sound is 330 m/s, then the frequency for the second note is

The fundamental note produced by a closed organ pipe is of frequencyf. The fundamental note produced by an open organ pipe of same length will be of frequency

If the velocity of sound in air is 336 m/s. The maximum length of a closed pipe that would produce a just audible sound will be

An organ pipe P¹ closed at one end vibrating in its first overtone and another pipe P² open at both ends vibrating in its third overtone are in resonance with a given tuning fork. The ratio of lengths of P¹ and P² is

A resonance air column of length 20 cm resonates with a tuning fork of frequency 250 Hz. The speed of sound in air is

A cylindrical tube, open at both ends, has a fundamental frequency f^o in air. The tube is dipped vertically into water such that half of its length is inside water. The fundamental frequency of the air column now is

If the length of a closed organ pipe is 1.5 m and velocity of sound is 330 m/s, then the frequency for the second note is

A pipe 30 cm long is open at both ends. Which harmonic mode of the pipe is resonantly excited by a 1.1 kHz source? (Take speed of sound in air = 330 ms^–1)

Two closed organ pipes, when sounded simultaneously gave 4 beats per sec. If longer pipe has a length of 1m. Then length of shorter pipe will be, (v = 300 m/s)
