List-I shows four configurations made of straight and semi-circular narrow tubes containing air. A sound wave of wavelength λ = 0.29 m enters these structures at the point S and a sound detector is placed at D. Between the points S and D, the sound travels only through the tubes. List-II contains the possible smallest values of l for which the detector D records maximum amplitude. Ignore effects of sharp corners. [Given cos15° = 0.97] Choose the option that best describes the match between the entries in List-I to those in List-II. Image

Two loudspeakers (L₁ and L₂) are placed with a separation of 10 m, as shown in figure. Both speakers are fed with an audio input signal of same frequency with constant volume. A voice recorder, initially at point A, at equidistance to both loud speakers, is moved by 25 m along the line AB while monitoring the audio signal. The measured signal was found to undergo 10 cycles of minima and maxima during the movement. The frequency of the input signal is _____ Hz
(Speed of sound in air is 324 m/s and √5 = 2.23)
