Medium is a form of communication (ex: newspaper, radio, television) and I would assume the answer would be live theatre seeing as that would be live medium.

(plural media or mediums) The nature of the surrounding environment, e.g. solid, liquid, gas, vacuum, or a specific substance such as a solvent.

A medium is the substance through which a wave can propagate. Water is the medium of ocean waves. Air is the medium through which we hear sound waves. The electric and magnetic fields are the medium of light.

1 : something that is in a middle position (as in size) 2 : the thing by which or through which something is done Writing is a medium of communication. 3 : the substance in which something lives or acts the medium of air.

An example of a medium is a newspaper from the combined media form of newspapers, television, magazines, radio and the Internet.

A medium is a substance or material that can carry a wave. The wave medium is not the wave and it does not make the wave; it merely carries or transports the wave from its source to other locations.

Do all waves require a medium to travel? Explain. No, electromagnetic waves do not require any medium to propagate. No, mechanical waves do not require any medium to propagate.

In terms of traveling waves (light included) the “medium” is the material the wave is passing through.

Mechanical waves require a medium in order to transport their energy from one location to another. A sound wave is an example of a mechanical wave.

Waves come in two kinds, longitudinal and transverse. Transverse waves are like those on water, with the surface going up and down, and longitudinal waves are like of those of sound, consisting of alternating compressions and rarefactions in a medium.

Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

Types of Waves in Physics

• Mechanical waves.
• Electromagnetic waves.
• Matter waves.

There are two basic types of wave motion for mechanical waves: longitudinal waves and transverse waves. The animations below demonstrate both types of wave and illustrate the difference between the motion of the wave and the motion of the particles in the medium through which the wave is travelling.

1 : to motion with the hands or with something held in them in signal or salute. 2 : to float, play, or shake in an air current : move loosely to and fro : flutter flags waving in the breeze. 3 of water : to move in waves : heave. 4 : to become moved or brandished to and fro signs waved in the crowd.

Primary waves (P-waves) are compressional waves that are longitudinal in nature. P-waves are pressure waves that travel faster than other waves through the earth to arrive at seismograph stations first, hence the name “Primary”. In air, they take the form of sound waves, hence they travel at the speed of sound.

P wave

P-waves are compression waves that apply a force in the direction of propagation. On the other hand, S-waves are shear waves, which means that the motion of the medium is perpendicular to the direction of propagation of the wave. The energy is thus less easily transmitted through the medium, and S-waves are slower.

Primary (compressional) waves They travel through the Earth’s interior and can pass through both solid and molten rock. They shake the ground back and forth – like a Slinky – in their travel direction, but do little damage as they only move buildings up and down.

Surface waves travel only through solid media. They are slower-moving than body waves but are much larger and therefore more destructive. The two types of surface waves are named Love waves and Rayleigh waves, after the scientists who identified them.

P waves travel at speeds between 1 and 14 km per second, while S waves travel significantly slower, between 1 and 8 km per second. The S waves are the second wave to reach a seismic station measuring a disturbance. The difference in arrival times helps geologists determine the location of the earthquake.
