Question

the time period of vibration of the particle of a medium is 2 into 10 to power minus 3 second and the wavelength of the corresponding wave is 3 metre find the speed of the wave in the medium​

Answer 1

Answer:

Frequency=1/Time taken

Frequency=1/2×10^-3

Frequency=500Hz

Speed=frequency×wavelength

Speed=500×3

Speed=1500m/s

Answer 2

Answer:

The speed of the wave in the medium​ is 1500 m/s

Explanation:

Given

time T = 2 X 10⁻³ s

wavelength λ = 3 m

speed v = ??

Solution

as we know that

f = 1/ T -----------(i)

also

v = f  λ ------------(ii)

comparing

v = λ/ T

putting values

v = 3 m / 2 X 10⁻³ s

v = 1.5 X 10³ m/s

v = 1500 m/s
