explanationthe general form of wave equation is y=Asin(kx-wt)we have y=5sin(3x-4t)hence the angular frequency w= 4s^-1the frequency f=w/2 pi f=4/2 pi f=4/2*3.14 f=0.64 hzthe periodT=1/fT=1/0.64T=1.5625=1.6the wavelengthk=2 pi/lambdalambda=2 pi/kk=3solambda=2*3.14/3lambda=2.09if my answer is right then mark me brainlistReply
The correct answer is c
i believe the answer is a
explanation
the general form of wave equation is
y=Asin(kx-wt)
we have
y=5sin(3x-4t)
hence the angular frequency
w= 4s^-1
the frequency
f=w/2 pi
f=4/2 pi
f=4/2*3.14
f=0.64 hz
the period
T=1/f
T=1/0.64
T=1.5625=1.6
the wavelength
k=2 pi/lambda
lambda=2 pi/k
k=3
so
lambda=2*3.14/3
lambda=2.09
