Question

Question 1 8 pts If the speed of a wave increases, the frequency must ALWAYS increase. True O False Question 2 8 pts Only odd harmonics are possible in a pipe closed at BOTH ends. True False

Answer 1

QUESTION -1 :

The relation between speed of the wave , wavelength and frequency are v = f $\lambda$
so, from the wave equation, the speed of the wave is directly proportional to frequency of the wave and hence if the speed increases, frequency must always increase.

so the answer is TRUE.

QUESTION-2:

For the pipe which is closed at both the ends, both odd and even harmonics are possible
and hence the answer is FALSE.
