- 1. APPLICATIONS OF Electro Magnetic E M WAVES – in everyday life – Iris Faith Jacob first of all… Electromagnetic Waves (EM Waves) are different mechanical waves in some important ways. They are disturbance that transmit energy through field. Since EM waves can transmit energy, it can be used to communicate long distances or even promote healing within the body by using certain applications. This belongs to the regions in the electromagnetic spectrum such as… RADIO MICROWAVE INFRARED VISIBLE LIGHT ULTRAVIOLET X-RAY GAMMA RAY • RADIO — A P P L I C A T I O N S — a sound communication using radio waves, usually through transmission of sounds. • OVENS a kitchen appliances that utilizes heat to cook food. • WI-FI a technology that makes use of microwaves for the transmission and reception of signals • INFRARED SCANNERS used to show temperature of the body and can be also used for medical diagnosis.

As human intelligence continues to develop, more utilities can be created, particularly to reduce time and effort. The importance of these things are beyond our hands as we use it. – end –
