P=wave is short for pressure wave. S-wave is short for shear wave. This should suggest a possible reason they behave differently in the (molten) outer core.
It's kinda like a fire if there is nothing to burn the fire wont go there, so with electrons if there is nothing to travel in to (like a switch, a light bulb, a buzzer ect.) the electrons wont go there because they can't just travel through air like fire can't just travel through air.
As during a thunder storm there is very little light from the sun. so the light cant travel through the rain drops. thus making it impossible to have a rainbow
You cant unless you know how many minutes you travel
you cant get to Jupiter with a car its in space! only if cars could fly
electricity can travel through anything with a positive and negative electrical charge
light can travel through a vacuum whereas sound cant
light cant travel through opague materials, or anything you cant see through.
it cant travel through light.
Why cant sound travel through empty space
Ocean
sound can't travel through a vacuum. or a place without air.
because electricity cant travel through them
sound cant travel on an asteroid because it has no atmosphere. it could travel through it.
There is no air for sound to travel through.
light can but sound cant as there is no air
Sound (and vibration) are a wave system of sequential compressions and rarefactions of a material. These waves are mechanical and do need a substance through which to travel. They cannot travel through a vacuum.
No medium to carry the sound energy.
