Answer:
Towers and satellite.
Explanation:
Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.
Generally, the most commonly used electromagnetic wave technology in telecommunications is radio waves.
Radio waves can be defined as an electromagnetic wave that has its frequency ranging from 30 GHz to 300 GHz and its wavelength between 1mm and 3000m. Therefore, radio waves are a series of repetitive valleys and peaks that are typically characterized of having the longest wavelength in the electromagnetic spectrum.
Basically, as a result of radio waves having long wavelengths, they are mainly used in long-distance communications such as the carriage and transmission of data.
The distance from one peak to the next peak is called wavelength. This distance is also equal to the distance from one trough of a wave to another.
Also, microwave is a form of radio waves which typically has short wavelengths and frequency ranging from 300 MHz and 300 GHz.
Hence, microwave transmits information between network nodes using towers and satellite.
Answer:
The correct answer for the given question is option(3) i. src.
Explanation:
In HTML if we insert a image on the screen we use<img> tag
the img have following attribute
1.src
2.height.
3 alt
4 width
The required attribute in img tag is src i.e source or path of image
The following are the syntax of image tag
<img src=" path of image" alt="not visible" height="100px" width="100px"/>
The height and width attribute describe the height and width of image in pixel.
The alt attribute is not mendatory attribute in image tag.The alt attribute display the message when image is not visible in the web page .
All the other attribute like alt,height,width are used as per the requirement but src is an required attribute .
so the option(3) is correct.
