velocity is displacement of a body in unit time...
i.e. velocity= displacement/ time
velocity= distance/time only when body covers equal distance in equal interval of time and in a particular direction.... i.e. straight line
velocity is a vector quantity as it has both direction and magnitude....
SI unit is m/s
hope it helps you....

answer : -
definition of velocity :-
velocity :)
the distance travelled by the wave in one second is called velocity.
it is expressed in m/s or cm/s
speed of all electromagnetic waves in vacuum is equal to 3 × 10 ^8 m/s ., it is denoted by c.since , c = 3 × 10 ^8 m/s.
relation between speed , frequency ,and wavelength.
speed = frequency × wavelength.
so , for electromagnetic waves in vacuum.
c = v × lamda or lamda = c /v
note :- lamda is si unit of wavelength.
velocity :)
it is a vector quantity they have magnitude as well as direction.
