Yes. Waves are of two types basically. One is mechanical which badly needs a material medium to traverse through. Example is sound wave which needs a material medium such as air, metal or liquid to pass through. So sound cannot pass through vacuum. Sound travels at a speed 330 m/s in air at NTP. If humidity in atmosphere increases then speed of sound also increases.
Another type is electromagnetic. It could pass even through vacuum. Light is electromagnetic by nature. Light travels at different velocities in different medium. In vacuum its velocity is 300,000 km/s but in glass it will be 200,000 km/s. Hence the refractive index of glass is found to be 1.5.

In what ways are sound waves and electromagnetic waves different?
They travel at different speeds.
How are water waves different from electromagnetic waves?
electromagnetic waves can travel through vacuum while water waves travel in water.
What produces standing waves-?
When two waves travel in a medium with the same speed and frequency but opposite velocities.
How are electromagnetic or light waves different from water and sound waves?
Light waves and electromagnetic waves can travel through empty space. Water waves can only travel through matter. Hope this helped!
When does two objects traveling at the same speed have different velocities?
When they travel in different directions, obviously, since velocity is made up of a speed and a direction.
Why do waves change speed as they travel through earths layer?
Different materials have different velocities of sound propagation.
What produces a standing wave?
When two waves travel in a medium with the same speed and frequency but opposite velocities.
How do waves travel in an earthquake?
different forms of waves
In what ways are sound waves and electromagnetic waves different?
They travel at different speeds.
How are water waves different from electromagnetic waves?
electromagnetic waves can travel through vacuum while water waves travel in water.
What waves have the highest velocities in earthquakes?
P waves (PRIMARY Waves) have the highest average velocity as they travel through the earth's materials.
How are sound and waves different from electromagnetic waves?
they are different because these waves can travel through empty space
What do different waves travel through?
surface waves can only travel along the surface.
What produces standing waves-?
When two waves travel in a medium with the same speed and frequency but opposite velocities.
Why does light refract?
Because light travels at different velocities, and various colors of light also travel at different speeds in optical media.
How are electromagnetic (or light) waves different from water and sound waves?
Light waves and electromagnetic waves can travel through empty space. Water waves can only travel through matter. Hope this helped!
