| (A) Amplitude | (1) frequency |
| (B) Frequency | (2) amplitude |
| (C) Loudness | (3)maximum displacement on either side |
| (D) Pitch | (4) presence of other frequencies |
| (E) Waveform | (5) 1/ time period |

Name musical instrument, one in each case, which produces its notes by using the following. In each case state the method used to produce notes of different pitches and loudness.
(a) A vibrating string.
(b) A vibrating column air.
(c) Vibration of any other body.
Name the subjective property of light related to its wavelength.
Two musical notes of the same pitch and loudness are played on a violin and a piano. Their waveforms are as shown in the figure below:
The frequency of the stretched string of a fixed length is f when it is plucked in the middle. Where should it be plucked so that string vibrates with frequency (i) 2f, (ii) 3f?
Draw diagrams to show these vibrations and name them.
Two waves of the same pitch have their amplitudes in the ratio 2 : 3.
(i) What will be the ratio of their loudness?
(ii) What will be the ratio of their frequencies?
