radio waves are electromagnetic waves describe how radio waves are different from sound waves

Radio Waves. ... However, sound and radio waves are completely different phenomena. Sound creates pressure variations (waves) in matter, such as air or water, or your eardrum. Conversely, radio waves are electromagnetic waves, like visible light, infrared, ultraviolet, X-rays, and gamma rays.

Are radio waves electromagnetic waves?

Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation. Electromagnetic radiation can be described in terms of a stream of mass-less particles, called photons, each traveling in a wave-like pattern at the speed of light.

What is the difference between radio waves and infrared waves?

The Difference between Radio Waves and Infrared Light. According to NASA, radio waves have a longer wavelength than infrared light, in the electromagnetic spectrum. ... Infrared light only functions through line of sight, whereas radio waves can effectively be used from a long distance.

How do radio waves produce sound?

Radio waves have the longest wavelengths in the electromagnetic spectrum. ... You can tune a radio to a specific wavelength—or frequency—and listen to your favorite music. The radio "receives" these electromagnetic radio waves and converts them to mechanical vibrations in the speaker to create the sound waves you can hear.

How would you describe radio waves?

Radio waves are a type of electromagnetic radiation best-known for their use in communication technologies, such as television, mobile phones and radios. These devices receive radio waves and convert them to mechanical vibrations in the speaker to create sound waves.

Can radio waves pass through human body?

Infrared light and radio waves

We can feel the heat of infrared light because its energy is absorbed mostly by the skin. On the other hand, we cannot feel radio waves because these emit their energy deeper in the body, under the heat-sensitive cells of the skin.

What are the dangers of radio waves?

RF radiation has lower energy than some other types of non-ionizing radiation, like visible light and infrared, but it has higher energy than extremely low-frequency (ELF) radiation. If RF radiation is absorbed by the body in large enough amounts, it can produce heat. This can lead to burns and body tissue damage.

What three ways do we describe waves?

All kinds of waves have the same fundamental properties of reflection, refraction, diffraction and interference, and all waves have a wavelength, frequency, speed and amplitude. A wave can be described by its length, height (amplitude) and frequency. All waves can be thought of as a disturbance that transfers energy.

What are the 7 types of electromagnetic waves?

The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.

What are the 7 electromagnetic waves in order?

In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves. Microwaves (like the ones used in microwave ovens) are a subsection of the radio wave segment of the EM spectrum.

How fast is a radio wave?

Radio Waves

They have have frequencies from 300 GHz to as low as 3 kHz, and corresponding wavelengths from 1 millimeter to 100 kilometers. Like all other electromagnetic waves, radio waves travel at the speed of light.

What is an example of a radio wave?

Radio wave, wave from the portion of the electromagnetic spectrum at lower frequencies than microwaves. ... They are used in standard broadcast radio and television, shortwave radio, navigation and air-traffic control, cellular telephony, and even remote-controlled toys.

What is a radio wave made of?

Radio waves are radiated by charged particles when they are accelerated. They are produced artificially by time-varying electric currents, consisting of electrons flowing back and forth in a specially-shaped metal conductor called an antenna.
