its because they have a high speed same as that of light 3x108 m/s.
Light is energy. Light is made of massless particles called photons that travel at the speed of light. Photons at a given frequency carry energy equal to the Planck constant times the photon's frequency.
Microwaves are a type of electromagnetic radiation with wavelengths ranging from approximately 1 millimeter to 1 meter. This range is situated between radio waves and infrared radiation on the electromagnetic spectrum. Microwaves are commonly used in various applications, including communication technologies, radar systems, and cooking appliances like microwave ovens. Their ability to penetrate materials and heat water molecules makes them particularly useful in food preparation.
Infrared waves are located between visible light and microwaves on the electromagnetic spectrum. They have longer wavelengths and lower frequencies than visible light, making them useful for applications like thermal imaging and communication.
cyber communication can be useful with looking for more information about studies.
Visible light, which lets humans and other animals see, is part of the electromagnetic spectrum. RF (radio frequency) waves are part of the electromagnetic spectrum. RF transmissions carry radio and television broadcasts. They have the lowest frequency. Microwaves are part of the electromagnetic spectrum. X-Rays are part of the electromagnetic spectrum and have the highest frequency..
Zenneck surface waves are electromagnetic waves that travel along the interface between two different mediums, such as air and the ground. They have the unique characteristic of being able to propagate over long distances with low attenuation, making them useful for communication and sensing applications. Zenneck surface waves are particularly suited for underground communication, wireless power transfer, and radar systems.
In Antarctica, technologies useful were heating, transport, refrigeration. how far south do you want?
Yes, laser beams exist. They are intense beams of light with specific properties that make them useful in various applications such as cutting, welding, medical procedures, and communication technologies.
Mainly visible light.
A microwave is not typically considered an ICT (Information and Communication Technology) tool. ICT tools are primarily associated with technologies used for communication, information processing, and data management, such as computers, smartphones, and the internet. While a microwave is a useful kitchen appliance for cooking and heating food, it does not facilitate communication or information exchange.
Sonar and satillite imagery
I think it's laser pointer pen.
