Awave is described by: y (x, t) = 5 m sin (100 mt + 2.5
tix) where x is in meters and t is in seconds. (a) what
is the period of the wave? (b) what is the wavelength?
(c) what is the amplitude? (d) what is the speed of
the wave? (e) in what direction does the wave move?
(f) sketch a graph of y(t) at x = 0 (g) sketch a graph of
v(x) at t = 0
