Question

The frequency of a wave:
A. increases with increasing period.
B. decreases with increasing period.
C. increases with increasing wavelength.
D. a and c only.

Answer 1

Hint:
by definition of frquency f and period T of a wave, we have:
\[f = \frac{1}{T}\]

Answer 2

Yeah I don't get it....

Answer 3

hint:
if T is increasing then the number 1/T will decrease

Answer 4

There s an inverse relation between T and frequency ,. Inverse proportionality shows that if one value is incresing the other must be decreasing or vice versa ...

Answer 5

1. The frequency of a wave decreases with increase in wavelength at constant wave velocity (because Frequency=velocity/wavelength)
2. The frequency decreases with increase in time period (because frequency=1/time period).
