Question

Find the displacement of a point on the string as a function of position and time.

Open in App

Solution

Antinodes are phase apart through $4 x$
$4 x = 15 c m$
$x = \frac{15}{4} c m$
$a = 0.850 c m$
$t = 0.0750 s$
Equation of wave can be written as
$y = A s i n (k x) . s i n (w t)$
$y = (0.85) sin [\frac{2 π x}{0.3 c m}] . sin [\frac{2 π t}{0.075 c m}]$ .
