10.3 A taut string is agitated by a mechanical oscillator, producing a transverse wave that is described by the equation
where time is measured in seconds, and lengths in meters. Find (a) the direction of travel of the wave, (b) the wave's
amplitude, (c) the wavelength, and (d) the frequency.
(a) i. Left to right
ii. Right to left
iii. Up to down
iv. Down to up
(b) m
(c) m
(d) Hz10.4 A wave is described by the equation y = A sin (2.3xí 1.8t), where lengths are measured in meters, and time in seconds.
What is the earliest time t (> 0) when the displacement of a particle at position x = 1.6 m is at a maximum?
