Regarding standing waves, consider the three
statements:
|- Resonance frequencies are always multiples of
the frequency of the first harmonic.
Il - The relationship between velocity and other
physical quantities is no longer valid, as it makes no
sense to speak of velocity for a stationary wave.
III - In one-dimensional waves, when there is a
fixed end and a free end, the number of bellies is
always a semi-integer.
Only the statement(s) is correct:
a) II
b) III
c) I and III
d) none
e) I and II
