Does Stretching a Slinky Affect Wave Speed?

[runicle]

Everybody loves a slinky HELP!

my variables

• f = frequency
• v = velocity
• y = wavelength

Due to the equation v = yf what other factors could change 'v'? does the material condition (stretched) have any factors to change speed.​

These are some answers of the questions I have done.

The speed of a pulse reaching to the end is the same speed coming back to the other end​

The Amplitude does not effect the speed since it does not have a special part to the equation v = yf​

"Question I'm on"

Does the material condition effect the speed (ex. stretched)​

"My answer to that, not really sure"

The material condition does not effect the speed, because it only effects the amplitude therefore not effecting the speed.​

Are my responses correct? I experimented my theories on a slinky.

Yes, your responses are correct. The material condition does not affect the speed of the pulse, only the amplitude. Experiments with a slinky can help to further confirm this.
