You might be surprised to learn that all of these activities, not just the lamp, involve electromagnetic waves. Finally the magic gives out visible light from it. If electromagnetic waves were mechanical, there would be no light, heat or life on Earth! Microwaves are used to heat our food, and to propagate the waves we need for cell phone service. They travel in a direction that is at right angles to the direction of the particles of the medium. Maxwell considered that it was a discovery, that light was an electromagnetic wave. They are the only, two, separate types of waves.

## Difference Between Mechanical and Electromagnetic Waves

A sound wave traveling through air is a classic example of a longitudinal wave. When seismologists began to study earthquake waves they noticed that only longitudinal waves were capable of traveling through the core of the Earth. A ripple is generated, and it moves out away from the point where we initiated it. Compression is the area in which the medium particles are close to each other , Rarefaction is the area in which the medium particles are far from each other. The waves are moving westward, so the particles move northward and southward.

## Wave Propagation: Mechanical Waves vs. Electromagnetic Waves

When a musician plucks a guitar-string, are generated which on reaching our ear, produce the sensation of music. One example of a mechanical wave is sound. Objects in motion are examples of kinetic energy. They are transmitted by both intermolecular forces and by collisions between the molecules. One example of a transverse wave is a water wave where the water moves up and down as the wave passes through the ocean. Not the electric force, not the magnetic force, but the electromagnetic force. Radio and microwaves are usually described in terms of frequency Hertz , infrared and visible light in terms of wavelength meters , and x-rays and gamma rays in terms of energy electron volts.

## What Are Some Examples of Mechanical Waves?

Mechanical waves and electromagnetic waves are two important ways that energy is transported in the world around us. Energy will begin to be transported through the slinky from left to right. Types of mechanical waves Transverse waves is the wave in which the vibration of the medium particles is perpendicular to the direction of the wave propagation and consists of crests and troughs. Simple, but subtle and elegant. X-Rays X-rays beat all other types of waves with a ultimately high frequency.

## What Are Some Examples of Mechanical Waves?

Now it can be seen that electromagnetic radiation can be considered as waves and particles. When comparing the speed of mechanical and electromagnetic waves, the former travels at low speed. You can create a simple wave by wiggling a rope up and down, and this is a mechanical wave. This activity causes the earthquakes. Each individual particle pushes on its neighboring particle so as to push it forward. Electromagnetic waves can do this because they do not rely on vibrating molecules.

## What are examples of transverse waves?

We are well familiar with different types of waves such as water waves in the ocean, or gently formed ripples on a still pond due to rain drop. The repeated cyclic transfer of energy from the electricfield weak … ening it to the magnetic field strengthening it untilthe electric field is gone, then from the magnetic field weakeningit to the electric field strengthening it until the magneticfield is gone every cycle is the process by which electromagneticwaves propagate without requiring a medium and is described inMaxwell's Equations. They can propagate in a vacuum. It is the only way a magnetic field can be created. Also, electromagnetic waves have the weird quantum property of sometimes acting like waves, and sometimes acting like particles.

## Examples and some technological applications of electromagnetic waves

At least surf on over and look at the drawing of the moving and electric and magnetic fields to lock that in. In a surface wave, it is only the particles at the surface of the medium that undergo the circular motion. Different waves travel at different speed. Transverse waves are waves where the disturbance moves perpendicular to the direction of the wave. Advertisement Waves transport energy without transporting matter.

## Types of Waves

Phase is the position and the direction of the medium particles at a certain instant , Complete oscillation is the motion of the oscillating body when it passes one point along the path of its motion twice successively in the same direction. Tsunami, floods are common destruction of water waves. Electromagnetic wave is type of radiation. This is similar to how sunglasses are able to eliminate glare by absorbing the polarized portion of the light. While the basic properties and behaviors of light will be discussed, the detailed nature of an electromagnetic wave is quite complicated and beyond the scope of. Swing of the perpendicular or right angle to each other forms the electromagnetic waves.

## What are three examples of electromagnetic waves

However, in all waves energy travels forward, and despite the shape of the wave the medium always returns to its starting point. In surface waves, both transverse and longitudinal waves mix in a single medium. In this case, the oscillating material moves about a fixed point and there is very little translational motion. There are two main types of waves, mechanical and electromagnetic. Because electrons in bonds can only accept one photon at a time, the number of photons aka the intensity of the radiation is irrelevant; only their strength matters.

## Difference Between Mechanical and Electromagnetic Waves

Waves are just one of them. In the above picture the top wave is transverse and the bottom wave is longitudinal. Waves come in many shapes and forms. They cannot travel through a vacuum like space. Sound waves cannot travel in the vacuum of space because there is no medium to transmit these mechanical waves.
