1.	A 100cm long stretched string is struck at a point 25 cm from one of its ends. Which of the overtones would be absent in the emitted notes ?
Answer» ANSWER :Atthe striking point, an amtinode would be formed. So, the overtones having a node at the point of 25 cm would not be formed . As 25 cm` = (100 cm)/(4) = (l)/(4) `( l = length of the STRETCHED string,) the absent overtones would be the 4TH , 8th , 12TH , ..... harmonics .
