Answer to Question #171805 in Physical Chemistry for ncssr

Question

A travelling wave is described by formula y(x, t) = A cos[(2pi/L).x - (2pi/T).t] where x and t represents position and time, respectively, and A is amplitude; L is wavelength and T is time period. What is the time period and wavelength of y(x, t) = 16 cos[(pi/30). x - (pi/10).t]

Answer 1

Time Period = 7 seconds

Wavelength =2 metres
