Question

use the relationship between period and frequency to explain that the universal wave equation is equivalent to the kinematics definition of speed

Answer 1

Kinematics definition of speed -->speed = distance / time.
Wave equation--->velocity =frequency * wavelength
frequency = 1/ time
so velocity = wavelength * time
now velocity is equivalent to speed and wavelength is equivalent to distance.....hence, these two are equivalent....

Answer 2

post physics question in physics section next time...

Answer 3

woops
sorry
and thanks for the answer

Answer 4

welcome :)

Answer 5

this is a explanation as per dimensions.................
but i do think that the question is not correct on physical standards reason being that........
1.wavelength is displacement of wave along an axis in which a wave repeats itself but what you have written is speed and which implies the distance travelled in unit second
2. now if the word speed is replaced by velocity then we can say
velocity is displacement per unit time
and also \[v=\lambda \times \nu\]
as time period= inverse of frequency
so \[v=\frac{ \lambda }{ t }\]
which means displacement per unit time hence as per kinematics we can say both are equivalent

Answer 6

wow!
