Electromagnetic waves (EM Waves) are radiations produced by concurrent periodic intensity variations in the magnetic and electric field. It includes X-rays, gamma rays, ultraviolet rays, infrared, and visible light. The waves have wide applications from healthcare, communication, to day-to-day life. The advancement in technology means that the use of electromagnetic waves can only expand. Innovations like driverless cars, drones, and robots among others all use electromagnetic waves as a primary form of communication and detecting the objects within their surroundings. This paper is a reflection of three articles looking at various aspects of the waves and its applications. The articles are scholarly works by multiple authors with good academic credentials making them reliable sources of information on the subject.
