Awave pulse is created in slinky it takes 1.2 seconds to travel the length of the slinky. if the slinky is 8 metrs long 1 wavelength, what is the speed of the wave?

The speed of the wave = 6.64 m/s.

Explanation:

Wave: A wave is a disturbance which travels through a medium and transfer energy from one point to another without causing any permanent displacement of the medium itself.

The velocity of a wave (v) = λf Equation 1

Where λ = wave length of the wave, f = frequency of the wave.

Given: λ = 8 m, and

f = 1/t where t = period.

t = 1.2 s

f = 1/1.2 = 0.83 hertz

Substituting these values into equation 1

v = 8 × 0.83

v = 6.64 m/s.

Therefore the speed of the wave = 6.64 m/s.

it takes about 30 days for it to break down

it's a b and
