Speed and velocity are never the same thing.
Velocity means 'speed' AND the direction it's going.
Velocity is a vector quantity that includes both speed and direction, while speed is a scalar quantity that only measures how fast an object is moving. The key distinction between velocity and speed is that velocity includes direction, while speed does not.
There are some situations in which waves move faster than the speed of light; but in no case can this be used to transmit matter, energy, or information, at a speed faster than the speed of light in a vacuum.
No, terminal velocity is the constant speed that a freely falling object eventually reaches when the upward force of air resistance equals the downward force of gravity. Shock waves are rapid changes in air pressure and temperature produced by an object moving faster than the speed of sound in a particular medium.
If the final velocity is less than the initial velocity, the object is decreasing speed. The object has slowed down or its speed has decreased compared to when it started.
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.

It isn't - at least, not in a vacuum. All electromagnetic waves have the same speed in the vacuum. Both visible light and x-rays are electromagnetic waves.

No as they are both electromagnetic waves so have the same velocity but have differing wavelengths and frequencies.
The size of the velocity is the speed, and you calculate it the same way. But whenyou find the size of the velocity, you're not done yet, because you also need itsdirection.

Speed and velocity cannot be compared because they are different things. It is like saying "apples > oranges". Velocity is a vector and, as such, it has a direction and a size. The size of the vector velocity is it's speed.To answer your question: no because they can't be compared. And if you wanted to ask if the size of the velocity vector being smaller than the speed... no... that is the definition of speed... so it cannot be different, regardless of the number of dimensions you are using.

Velocity, which is different than speed in that it has a directional component to it.
