1.	Whichof the tones will be absent in the note emitted from a string clamped at both ends, when it is struck at a distance of one-third or its length from one end ?
Answer» Answer :Thestretched string AB (Fig . 4 . 19] is struck at the point C , where ` AC = (1)/(3)AB` . As a result, an antinode will beformed at C : a node can never be FORMED there . So the modes of vibration, as shown in the figure, will be absent. This MEANS that the absent tones would correspond to the 3rd 6th 9th .....harmonics `(##CHY_DMB_PHY_XI_P2_U10_C04_E01_002_A01##)`
