Open Answer ยปKanika carried out an experiment on determination of speed of sound in air using resonance tube apparatus and obtained absurd results. She should (a) record the result as such. (b) manipulate the result and report the answer nearer to actual value of velocity of sound in air. (c) copy the result obtained by another student.

Figure shows a loudspeaker cone oscillating to produce sound waves: (๐) As the sound wave passes a point, it produces regions of higher and lower pressure. State the names of these regions. (๐) Describe how the movement of the loudspeaker cone produces these regions of different pressure. (c) State the effect on the loudness and pitch of the sound from the loudspeaker when (๐) the amplitude increases but the frequency of the sound stays the same, (๐๐) the amplitude stays the same but the frequency increases.
Open Answer ยป Represent graphically any two separate diagrams in each case: (๐) Two sound waves having the same amplitude but different frequencies. (๐๐) Two sound waves having the same frequency but different amplitudes. (๐๐๐) Two sound waves having different amplitudes and also different wavelengths.
