Longitudinal waves have compressions and rarefactions and im sure you know that the distance between the centres of two compression or two rarefactions is the wavelength.
However, to work out amplitude you must know that at the centre of the rarefaction or at the centre of a compression the displacement is zero. Using that and the slinky given at the rest position, you can work out the distance between the maximum displacement of the slinky.

could u plz elaborate a bit more if i assume the centre of the rarefaction or at the centre of a compression the displacement is zero then what i am supposed to measure using the slinky at rest position....
i would appreciate if u could use the uploaded file and put marks wht exactly to measure as that would be really helpful
Thanks

You can't actually. You have to measure from compression to compression or rarefaction to rarefacton.

Seems an easy momentum question..
A 4MeV particle collides head-on with a stationary proton, and its kinetic energy is reduced to 1MeV. What is the mass of the particle? Mass of a proton = 1.6726*10-27kg.
But I can't get it.

does anyone have any notes on the nature of light?please i need it urgently..
Meticulous:
