Waves travel through each other.
When waves of the same frequency are in phase they reinforce each other when their peaks and valleys occur at the same point. They add up.
P-waves can pass through liquids,solids,and gases. A P-wave is a type of body wave that has an up and down motion. Another type of body wave is the S-wave. S-waves CAN'T pass through liquids but they can pass through solids and gases. I hope that answered your question. =)
The speed of the waves that travel through the interior can tell the density of each layer of the Earth. Some waves can make it through certain layers, but not others.
Sound (unlike ocean waves) is a pressure wave, not a transverse wave. Pressure waves (as the name suggests) are waves the oscillate in the direction that they are moving, hence have a pressure difference. If you bang a piece of steel with a hammer, then you are momentarily changing the pressure in the steel at that point. The pressure change moves along very rapidly, and your ears pick that up as sound. Because the atoms in a solid are much closer together than the atoms in a gas, sound can travel much, much faster in a solid than a liquid or a gas.
Because when you put the north end of the magnet of the north end on the other magnet, or vise versa, it repells, which is when they bounce away from each other.
They look like before they pass through each other.
its call superposition
Molecules (atoms, ions) bounce each other.
the light goes through it and travels with each other.
Standing Waves.
They can not hear each other through the natural environment due to there being no medium for the sound waves to travel through. However, they can hear each other through the use of radio communication.
elasticity
For the same reason that charges can attract or repel each other through nothing, magnets can attract or repel each other through nothing, (and masses can attract each other gravitationally through nothing). Electric and magnetic 'fields' can be felt at a distance without anything to help spread their influence. Light and all other electromagnetic waves are the result of electric and magnetic fields in space.
because there is nothing but empty space and the partcles cant bounce and vibrate against each other
There are two main types of EM waves. Magnetic waves and Electronic waves. They exist at orthogonal relationships with M waves and E waves at 90 degrees to each other.
we use waves to comunite each other
because the sound waves travel through the metal of the helemets.
