Question

the displacement wave is represented by y=Asin(wt-kx)

x is the distance
t is the time
write dimensional formula for w and k....

here w means omega...sry....plss help..urgent...

Answer 1

wt=constant
w=constant/time
hence omega dimension is [T^-1]
actually w is angular velocity
e.g w =2.pi/T
where T is time period.

again
Kx =constant
K=constant/x
dimension of K =[L^-1]
K is known as phase constant
e.g K =2pi/lemda

Answer 2

The dimensional formula for omega is. Now,
