For the same reason anything else changes velocity in a different medium, I would say. A change of electromagnetic impedance in this case

What is the moho in the earths layers?
The Mohorovicic Discontinuity is the boundary between the crust and the mantle, where seismic waves change velocity.
Do p waves or s waves have higher velocity?
P waves have a higher velocity than S waves. This is known because P waves (Primary waves) arrive at recording stations faster than all other waves. S waves (Secondary waves) arrive second at recording stations.
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.
What does Geosat measure?
a.the height of the ocean b. the change in the oceans land forms c.the direction and speed of the oceans currents or d.the velocity of the waves hitting the shore
What are earthquake generated waves called?
Earthquake generated waves are called seismic waves. These are waves of energy that travel through the Earth's layers. Their velocity depends on the elasticity and density of the medium that they travel through.
Does temperature depends on sounds waves?
yes bcoz for different temperature we have different mediums.....
What type of mediums are ocean waves?
Ocean waves are NOT mediums of any sort.
Why do waves change direction when they travel between one material and another?
Because they are changing mediums.
What are types of wave mediums?
Ocean waves are NOT mediums of any sort.
Are wave speeds dependent on material?
Yes, wave speeds are dependent on the material through which the wave is propagating. Different materials have different properties that affect how quickly a wave can travel through them. For example, sound waves travel faster in solids than in liquids or gases. Similarly, electromagnetic waves, such as light, travel at different speeds in different mediums, with the speed being fastest in a vacuum.
What do you call waves that bend when changing mediums?
Waves are said to have been refracted when they bend upon changing mediums. The waves have undergone refraction when moving from one medium to another.
Does the velocity of two different waves in the same medium be equal?
no it is not equal
Does the same wave travel at different speeds in different mediums?
Short Answer:The speed of a wave depends very much on the type of the wave and the medium though which it moves.More:Sound waves in air, water waves in the ocean and light waves in space are waves different waves in different mediums and with vastly different speeds. Each of these types of waves changes speed dramatically in different media. Ripples move at a different speed than ocean waves. Light in glass travels at about two thirds of the speed of light in a vacuum and sound waves in metal are much faster than sound waves in air. Another good example is waves from an earthquake, which occur in two different forms and which are regularly experienced as separate shocks from an earthquake.
What Waves Resemble Transverse Waves But Occur In Mediums That Are Fixed At Both Ends?
standing waves
What are three medium waves can travel through?
Not all waves require mediums to propagate.Sound waves can travel through solid, liquid and gaseous mediums, while, electromagnetic waves do not require any medium to travel through.
Why do waves bend when they go through different mediums?
Because everything even though you can't see them, have physical particles.
How are light and sound waves different in terms of speed type of wave and mediums?
Light waves travel at approx 300,000 kilometres per second, sound at approx 0.343 kilometres/second.Light waves can travel in vacuum or through some media (there is no such word as mediums!). Sound waves cannot travel through vacuum: they needs a physical medium.
