Refraction. Like when you put your hand in the pool and your fingers look stubby.
Yes, Refraction is the change in direction of a wave due to a change in speed. For example, a straw in water bends as it goes through the medium of the water, so it may go through any medium which speed changes.
Refraction is the bending of light when it passes from one medium to another medium (like from air to glass). The basis for refraction is the speed of light is slightly different in the two mediums. Diffraction is the bending of light that occurs around a sharp edge (like light passing thru a slit). The basis for diffraction is the spreading out of the wave as it passes by the sharp edge.
Doppler Effectits actually called refraction

Refraction.
It is the refraction of light.
It is the refraction of light.
This sounds like refraction.
That's "refraction".Note:The bending of light is due to its change in speed.Bending alone would constitute a change in velocityeven if speed didn't change.
diffraction
The speed of the wave stays same but the frequency change due to motion.

Three ways that waves change direction are reflection, refraction, and diffraction.
Mechanical Waves:1.Mechanical waves need a material medium for their propagation.2.These waves are produced due to the vibrations of the particles of the medium.3.They have low speed.Electromagnetic Waves:1.Electromagnetic waves do not need any material medium for their propagation.2.They are caused due to change in electric and magnetic fields.3.They have high speed.
