Question

find the dimension of x if y = Sin ( xt) where sin Q is dimension less​

Answer 1

Answer:

In the given equation y=Asin(ωt−kx)

Since, trigonometric function is a dimensionless quantity. So, (ωt−kx)is also dimensionless quantity.

So,

(ωt−kx)=1

ωt=1

[ω]= [T]1 =[T] −1kx=1[k]= [L]

1 =[L]

−1

Answer 2

which one will you choose t or d?
