Hi,

Which correctly expresses the relationship between wavelength (L), speed (V) and perios (T) of a sinusodial wavform ?

a) L = T/V

b) L= 2fxV/ T

c) L= 1 / V x T

D) L= V/T

e) L = V x T

f) L= V x T/ 2f

I feel it is option (d) ..please check for me ..

and thanx

1. Is it possible to do some thinking?

the wave equation is

frequency*wavelength=velocityofpropagation

but frequency is 1/period
so therefore,
wavelength= period*velocity.
