Mechanical and Electromagnetic waves
Waves are considered any oscillation that transfers energy and momentum. They involve the transport of energy without the transport of matter.

Doppler Effect
Sound: Vibrations that travel through mediums such as gas, liquid, and solid in the form of a mechanical wave. These waves are created by vibrating objects which set particles in the surrounding medium to vibrational motion, thus transporting energy through the medium.
The doppler effect is the apparent change in the frequency of a wave caused by relative motion between the source of the wave and the observer. In simpler terms, the doppler effect occurs when the source of waves moves and the waves bunch up in the direction of the source's motion. The waves also spread out behind the source as it moves.

How does medium affect speed of sound?
Example
A duck is stationary in a pond while causing ripples to form around it. A boy stands on the edge of the pond in front of the duck and a girl stands behind it. Right now, the boy and girl see that the ripples emit at the same frequency. The duck begins moving towards the boy. The boy now sees that the ripples occur more frequently while the girl sees less ripples over a period of time. This scenario can be explained by the doppler effect.
The elasticity of a medium (or its tendency to maintain its shape despite external force) plays an impact on the speed of sound. Because solids such as metal tend to be more elastic, speed travels faster through them. Sound travels slower through liquids and even slower through gases due to their respectivly decreasing elasticities. The more dense a material is, the faster waves travel through it. This is because when mass density of individual particles is increased, their responsiveness to neighboring particles decreases. Temperature also affects the speed of sound. Molecules at higher temperatures vibrate more frequently and thus transfer sound waves faster. At normal atmospheric pressure and dry air, the speed of sound waves based on temperature is as follows: v = 331 m/s + (0.6 m/s/C) * T

Speed Of EM Waves in a Vacuum
The speed of EM Waves in a vacuum is equivelent to that of light. The speed of light, commonly denoted as "c" in physics, is approximately 3.0 * 10 ^8 or 300 million m/s.
