Question

Choose the correct option:

$\begin{array}{cccc}1.& \text{Tone}& \text{i.}& \text{frequencies that are integral multiple of fundamental frequency}\\ 2.& \text{Note}& \text{ii.}& \text{sound of single frequency}\\ 3.& \text{Overtone}& \text{iii.}& \text{sound of multiple frequencies}\\ 4.& \text{Harmonic}& \text{iv.}& \text{higher frequencies other than fundamental frequency}\end{array}$

• A. 1 - ii, 2 - iii, 3 - iv, 4 - i.
• B. 1 - iii, 2 - ii, 3 - iv, 4 - i
• C. 1 - ii, 2 - iii, 3 - i, 4 - iv
• D. 1 - ii, 2 - iv, 3 - iii, 4 - i

Answer 1

The correct option is A

1 - ii, 2 - iii, 3 - iv, 4 - i.

• Sound of single frequency is known as tone and the sound of multiple frequencies is known as note. For example a musical note has tone of various frequencies (pitch) and amplitude (loudness).
• Pitch depends upon frequency of sound, it distinguishes between shrill and flatter sound. Higher the frequency of sound waves implies higher its pitch .
• The speed of sound depends upon the elasticity and the density of a medium through which it is travelling. The greater the elasticity and lower the density of material, faster the sound travell in medium.
