Which of the following is an electromagnetic wave?

An electromagnetic wave can travel through anything – be it air, a solid material or vacuum. … Electromagnetic waves can be split into a range of frequencies. This is known as the electromagnetic spectrum. Examples of EM waves are radio waves, microwaves, infrared waves, X-rays, gamma rays, etc.

What are electromagnetic waves quizlet?

What is electromagnetic waves and its properties?

Every form of electromagnetic radiation, including visible light, oscillates in a periodic fashion with peaks and valleys, and displaying a characteristic amplitude, wavelength, and frequency that defines the direction, energy, and intensity of the radiation.

What is meant by electromagnetic waves?

Radiation that has both electric and magnetic fields and travels in waves. It comes from natural and man-made sources. Electromagnetic radiation can vary in strength from low energy to high energy. It includes radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays, and gamma rays.

Where is energy stored in electromagnetic waves?

The E and B fields, along with being perpendicular to each other, are perpendicular to the direction the wave travels, meaning that an electromagnetic wave is a transverse wave. The energy of the wave is stored in the electric and magnetic fields.

How do electromagnetic waves travel quizlet?

Electromagnetic waves can travel through matter as well as across space. When they strike matter, they interact with it in the same ways that mechanical waves interact with matter. They may reflect, refract or diffract (bend around objects).

What do all electromagnetic waves have in common?

All electromagnetic waves have two wavefronts, which are an oscillating electric field and an oscillating magnetic field.

What is the most important electromagnetic wave?

The most important of these is visible light, which enables us to see. Radio waves have the longest wavelengths of all the electromagnetic waves. They range from around a foot long to several miles long.

How do you detect electromagnetic waves?

To detect the electric fields, use a conducting rod. The fields cause charges (generally electrons) to accelerate back and forth on the rod, creating a potential difference that oscillates at the frequency of the EM wave and with an amplitude proportional to the amplitude of the wave.

Can electromagnetic waves harm you?

There is no doubt that short-term exposure to very high levels of electromagnetic fields can be harmful to health. … Despite extensive research, to date there is no evidence to conclude that exposure to low level electromagnetic fields is harmful to human health.

What are the applications of electromagnetic waves?

They are used to transmit short or long or FM wavelength radio waves. They are used to transmit TV or telephone or wireless signals and energies.
