They travel at the same speed through air.They travel at the same speed through a vacuum.They are both transverse waves.
Other answers that are accepted: they can be reflected, refracted, diffracted,...

We know that the object is moving at 5m/s already telling us that the distance the object has travelled increases with time. Plotting distance on the y axis against time on the x axis we therefore expect ...

Molecules in the air encounter an energy source, they gain energy and begin to heat up which causes them to vibrate faster and become less dense which causes them to rise. As they rise, they begin to lose...

Ice, in it's solid form, is at a maximum temperature of zero degrees Celsius. You might expect that a small volume of Ice might cool say a 25 degree drink to somewhere halfway between 0 and 25. This is no...

To determine the kinetic energy of the car, we need to use the formula for kinetic energy. The formula is KE=(1/2)mv^(2) where m is the mass of the object (in kg) and v is the speed of the object (in mete...
