What type of wave is created by solar energy?

electromagnetic wave

How are waves used in technology?

Radio waves are used for communication such as television and radio. Radio waves are transmitted easily through air. They do not cause damage if absorbed by the human body, and they can be reflected to change their direction. These properties make them ideal for communications.

What inventions use waves?

The telephone and phonograph use mechanical waves to create a clear pitch for us to hear. Other inventions like spectacles, the telescope and microscope use electromagnetic waves to create clear images that our eyes would not pick up themselves.

How long is a radio wave?

Radio waves have the longest wavelengths in the EM spectrum, according to NASA, ranging from about 0.04 inches (1 millimeter) to more than 62 miles (100 kilometers). They also have the lowest frequencies, from about 3,000 cycles per second, or 3 kilohertz, up to about 300 billion hertz, or 300 gigahertz.

Who discovered waves?

Heinrich Hertz

What technological inventions are ultrasound waves used in?

Here are just a few of them:

Truly hands-free phones.
Acoustic holograms.
Glasses for blind people.
Tractor beams.
Martian scanners. Ultrasound technology is already being investigated as an exploration tool.

How do humans use ultrasound waves?

Ultrasound imaging or sonography is often used in medicine. In the nondestructive testing of products and structures, ultrasound is used to detect invisible flaws. Industrially, ultrasound is used for cleaning, mixing, and accelerating chemical processes.

How do you read an ultrasound picture?

Determine the visible side of the body. Most ultrasound images are mirrored, meaning you see the left side of the body on the left side of the image. If you have a transvaginal ultrasound, though, it uses a straight shot. A straight shot will show the left side of the body on the right side of the image.
