Question

Derive d formula
Velocity = frequency x wave length

Answer 1

v=f*lameda
derivation:-
as wavelength =distance travelled by the wave in one time period i.e,in T second
= wavevelocity*time period
=v*t and
VT= lameda(wavelength)...............(1)
as we know T=1/f
therfore,from(1)
V=f*lameda

Answer 2

hope this helps you...
