Mar 13, 2020 · Types of Electromagnetic Waves. There are seven types of electromagnetic waves – radio wave, microwave, infrared, visible light, ultraviolet, x-rays, and gamma rays. 1. Radio waves. As the name suggests, radio waves are emitted by radio stations, TV stations, and cellphone towers. They have a wavelength range of 1-10 5 meters.
Sep 9, 2024 · Electromagnetic waves are energy waves that travel through space, consisting of oscillating electric and magnetic fields perpendicular to each other. They include radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. These waves can travel through a vacuum at the speed of light and are essential in technologies ...
Applications of Electromagnetic Waves. Following are a few applications of electromagnetic waves: Electromagnetic radiations can transmit energy in a vacuum or using no medium at all. Electromagnetic waves play an important role in communication technology. Electromagnetic waves are used in RADARS. UV rays are used to detect forged bank notes.
- Velocity of an electromagnetic wave is a property which is dependent on the medium in which it is travelling. Other properties such as frequency, t...
- Since infrared light is a part of electromagnetic spectrum, the relation between the wavelength, frequency, and velocity is given by the formula: \...
- The given statement is true. Any wave from the electromagnetic spectrum travels at a constant speed of light. Other properties such as frequency, e...
- Photons can travel at a speed of light while other particles cannot because they do not have mass.
- The given statement is true. It is true that for increasing the accuracy, the frequency of propagation needs to be high.
- The sequence for the propagation of electromagnetic waves is the generation, propagation, reflection, and reception.
Jul 19, 2022 · Electromagnetic waves definition: The waves produced when an electric field comes in contact with the magnetic field are called electromagnetic or EM waves. They are a composition of oscillating magnetic and electric fields that can be studied using Maxwell’s equations. Electromagnetic waves can be radio waves, microwaves, television waves ...
Oct 9, 2020 · This is because electromagnetic waves can transmit energy through a vacuum, or without a medium. Here are a few applications of electromagnetic waves in our lives.
