Consider the wave `y = (5 mm) sin[1 cm^(-1) x - (60 s^(-1)) t]`. Find (a) the ampitude, (b) the angular wave number, ( c ) the wavelength, (d) the frequency, (e) the time period and (f) the wave velocity.

Explanation

(a) amplitude A = 5 mm , (b) wave number `k=1cm ^(-1)` , (c ) wavelength `lambda=(2pi)/k=2pi cm `
(d) frequency v `=(omega)/(2pi)=(60)/(2pi)Hz` , (e ) time period T`=1/v=(pi)/(30) s`
(f) wave velocity u `= nlambda =60 cm //s`
