Question #27002

y(x,t)=8sin(300t-0.15) where x in m ,y in cm and t in second what is the wavelength,frequency,wavespeed

Expert's answer

We have: y(x,t)=8sin(300t-0.15x)

Because the wave equation is y(x,t)=Asin(wt-kx)

so, frequency=(w/(2*pi))=150/pi

wavelength= 2*pi/k =pi*(13,(3)) (m)

wavespeed= wavelength*frequency=w/k= 2000 (m/s)

Because the wave equation is y(x,t)=Asin(wt-kx)

so, frequency=(w/(2*pi))=150/pi

wavelength= 2*pi/k =pi*(13,(3)) (m)

wavespeed= wavelength*frequency=w/k= 2000 (m/s)
