In a plane progressive wave given by $y = 25 \cos(2 \pi t - \pi x)$ , the amplitude and frequency are respectively
Text Solution
Verified by ExpertsThe correct answer is:
B
Given equation is
$y = 25 \cos(2 \pi t - \pi x) \dots (1)$
Standard equation is
$y = A \cos(\omega t - kx) \ldots (2)$
Comparing (1) and (2),
Amplitude, $A = 25, \omega = 2 \pi, k = \pi$
$\therefore \text{Frequency, n} = \frac{\omega}{2 \pi} = \frac{2 \pi}{2 \pi} = 1 \text{ Hz}$
