What are long wavelengths?

Long wavelengths refer to electromagnetic waves that have a low frequency and low energy. These waves have a greater distance between their peaks, such as radio waves and microwaves. They are typically used for communication and have the ability to travel long distances.


What is a positive effect of electromagnetic waves?

One positive effect of electromagnetic waves is their use in communication technologies such as radio, television, and cell phones, which allow for long-distance communication in real time. Electromagnetic waves are also used in medical imaging techniques like X-rays and MRI to diagnose and treat various health conditions.


Is scientific theories ever proven?

There was once a theory, that electromagnetic waves might be used for communication over long distance. Your mobile phone is the proof that the theory was correct.


What are three advantages of an electromagnetic?

Speed: Electromagnetic waves travel at the speed of light, making them extremely fast for transmitting information. Long range: Electromagnetic waves can propagate over long distances without the need for a physical medium, allowing for wireless communication. Versatility: Electromagnetic waves can be easily modulated for different applications such as radio communication, radar, and medical imaging.


What can be found in the form of waves or signals in both exosphere and ionosphere.?

In both the exosphere and ionosphere, you can find electromagnetic waves or signals. These can include radio waves, microwaves, and other forms of electromagnetic radiation. The ionosphere specifically can reflect and refract these waves, allowing long-distance communication via bounce or propagation.


What has the greatest period in the electromagnetic spectrum?

the electromagnetic spectrum with the smallest frequency will have the greatest period.In conclusion, because Radio Waves have the lowest frequency they therefore have the greatest period.


What do electromagnetic waves do in the process of communication?

Electromagnetic waves are used in communication to carry information through the air or space. They transmit signals between devices like radios, cell phones, and satellites, allowing for the exchange of data and messages over long distances.


What are the characteristics of radio waves and how do they differ from other types of electromagnetic waves?

Radio waves are a type of electromagnetic wave that have long wavelengths and low frequencies. They can travel long distances and penetrate obstacles like walls. Unlike other types of electromagnetic waves, such as visible light or X-rays, radio waves have lower energy levels and are used for communication and broadcasting purposes.


What type of electromagnetic radiation is commonly used for long-distance communications?

In technology, radio waves or microwaves are typically used.In our day-to-day communication (WITHOUT technology), we also use visible light.


In what ways are sound waves and electromagnetic waves different?

Sound waves require a medium to travel through, while electromagnetic waves can travel through a vacuum. Sound waves are mechanical waves that require particles to propagate, while electromagnetic waves are made up of oscillating electric and magnetic fields. Sound waves are slower than electromagnetic waves and are typically used for communication over short distances, while electromagnetic waves can travel long distances at the speed of light.


This layer is responsible for the possibility of radio communication?

The ionosphere is the layer responsible for enabling long-distance radio communication by reflecting radio waves back to Earth. Its charged particles interact with radio waves, bending and reflecting them to facilitate communication over long distances. Without the ionosphere, radio waves would continue into space, limiting long-distance communication possibilities.


Why acoustic waves concept is used instead of electromagnetic waves in under water communication?

Acoustic waves are used in underwater communication because they can travel long distances in water due to lower absorption and scattering compared to electromagnetic waves. Electromagnetic waves, such as radio waves, are quickly absorbed by water, limiting their range and effectiveness for underwater communication. Acoustic waves are also less affected by obstacles and can penetrate through water more effectively.
