Best answer: How does electromagnetic wave behave?

Light waves across the electromagnetic spectrum behave in similar ways. When a light wave encounters an object, they are either transmitted, reflected, absorbed, refracted, polarized, diffracted, or scattered depending on the composition of the object and the wavelength of the light.

How do electromagnetic waves travel?

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.

Do electromagnetic waves behave like sound waves?

Electromagnetic waves are not like sound waves because they do not need molecules to travel. This means that electromagnetic waves can travel through air, solid objects and even space.

How do mechanical and electromagnetic waves behave?

Mechanical waves cause oscillations of particles in a solid, liquid or gas and must have a medium to travel through. Electromagnetic waves cause oscillations in electrical and magnetic fields. It is important to remember that all waves transfer energy but they do not transfer matter .

Are electromagnetic waves longitudinal or transverse?

Electromagnetic waves are transverse waves. That means the electric and magnetic fields change (oscillate) in a plane that is perpendicular to the direction of propagation of the wave. Also note that electric and magnetic fields in an EM wave are also perpendicular to each other.

How does an electromagnetic wave carries energy from place to place?

In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels. In water waves, energy is transferred through the vibration of the water particles.

What is characteristics of both sound waves and electromagnetic waves?

Unlike water waves, electromagnetic waves always travel at the same speed (3 hundred million metres per second) and sound waves all travel at the same speed in a given medium (for example, approximately 340 metres per second in air). The speed of a wave is related to both its frequency and wavelength.

How can electromagnetic waves interrupt?

What are three properties of electromagnetic waves quizlet?

What are three properties of electromagnetic waves? They travel slower than the speed of light, they include visible light waves, and they can transfer energy through empty space. They need matter through which to travel, they travel at the speed of light, and they include visible light waves.
