Electromagnetic waves are produced by the acceleration of an electric charge. Electromagnetic waves have the same speed in a vacuum (or space). They can slow down and change direction.

What kind of waves does a light have?
The type of wave of a light wave is a transverse wave, like waves at the beach (surface waves). Transverse simply means that the motion of the wave is perpendicular to the direction of the wave. Simply put, if you're floating on the water, and a wave comes to you, the wave lifts you up, and then you drop back down as the wave passes. You are moving at a right angle to the direction that the wave is moving. This is why surfing is difficult, because you're trying to get it to push you, rather than simply lift you.Sound waves are longitudinal waves; they push particles in the same direction that they are moving in. Pressure waves from explosions are also longitudinal waves.
What are electromagnetic waves with the longest wave lengths and the electromagnetic waves with the shortest wave lengths?
The longest wavelength corresponds to long wave radio, I think the longest used is about 2000 meters. The shortest are gamma rays, which occur in radioactivity, these are from about 10-11 meters down.
How are EM waves like ocean waves?
Yes.Waves transmit energy, but not matter. In a longitudinal wave, the molecules move to and fro parallel to the direction in which the wave advances. Sound waves are longitudinal waves made up of a series of compressions and rarefactions. In a transverse wave, the molecules move back and forth at right angles to the direction in which the wave advances. A wave on the surface of a body of water is a transverse wave.Electromagnetic waves are also transverse waves. In electromagnetic waves, electric and magnetic fields-rather than molecules-move back and forth.
Describe the movement of a transverse wave?
In a transverse wave, either the matter or the disturbance moves at right angles to the direction in which the wave advances. Please note that not all waves involve moving matter. In the case of an electromagnetic for example, the change that is propagating is a disturbance in the electric and magnetic fields.
Do sound sound waves travel up or down and back or forth?
Back and forth in the direction of propagation of the sound waves.

What is it called when waves change there speed when they go in to different matereals?
This is related to a change in direction. The change in direction is called refraction. The numbers that describe HOW MUCH the speed of the wave slows down is called "index of refraction", especially in the case of light waves.
Is a radio wave mechanical or electromagnetic wave?
Radio waves are electromagnetic. That's how they can get down here from satellites.

How do you demonstrate transverse waves?
Water waves are known as transverse waves because the motion of the water is up and down, or at right angles to the direction in which the waves are traveling. You can see this by observing a cork bobbing up and down on water as the waves pass by; the cork moves very little in a sideways direction.

What waves don't need matter to travel through?
Electromagnetic Waves do not require a medium, or matter to move through, to transfer waves. This includes radiowaves, microwaves, infared waves, visible light waves, Ultraviolet waves, X-rays, and gamma rays.
What s waves move at angles to the direction of movement?
side and up/down
Do sound sound waves travel up or down and back or forth?
Back and forth in the direction of propagation of the sound waves.
How sound waves can be modelled with water waves?
Not very well, because they're different types of waves. They have some similar properties, but water waves are transverse waves (the water goes up and down, perpendicular to the direction of travel) and sound waves are longitudinal waves (the air vibrates parallel to the direction of travel).
What is the two differences between AC and DC?
Alternating current is bi-directional current that changes its direction frequently in circuit wheras Direct current is uni-directional current that does not change its direction when flowing in a circuit. In transformer(be it step up or step down) ONLY AC is used.This is because the direction keeps on changing so due to this the magnetic field also varies.So this leads to electromagnetic induction and there by this is the principle of a transformer. DC cannot be used in this because the direction does not change and due to this there is no change in the magnetic field and thereby electromagnetic induction does not take place
