Need help with questions about Waves on a spring

[ksuh]

1. Does the speed of the wave change as it travels along the slinky? (Would this be yes? Because it should slow down as it reaches the end of a slinky right?)
2. Does the speed depend on the size of the wave pulse?
3. When you change the tension in the spring, does the wave speed change? (My teacher never really explained tension so I'm a bit lost)

I'm just really lost and these questions have to be turned in tomorrow. Thanks in advance.

No wave velocity is constant for a given media. However your answer holds if you're discussing about particle velocity.

2. Does the speed depend on the size of the wave pulse?

Huh? Size of wave pulse means instantaneous vertical displacement or amplitude ?

3. When you change the tension in the spring, does the wave speed change? (My teacher never really explained tension so I'm a bit lost)

What is the formula relating to frequency and tension in a spring ? Does that involve wave velocity. Also what is the formula for wave velocity in a spring (transverse wave) ?

I'm just really lost and these questions have to be turned in tomorrow. Thanks in advance.
