How do we use electromagnetic waves in everyday life?

Radio waves are used for communications and radar. Microwaves are used to cook your food. Infrared waves are used in remote controls and are emitted from all warm objects, allowing them to be used to create heat-sensitive cameras.

What are the benefits of electromagnetic waves?

The killing and destructive power of electromagnetic radiation can be used constructively for curing the incurable diseases by eradicating the disease producing pathogens and micro organisms like bacteria, virus & fungi.

What are some medical uses of electromagnetic waves?

Applications involving heat-generating RF waves are used for therapeutic purposes. The three main EMF applications and areas of medicine using EMF sources are: • MRI – diagnostic imaging • RF ablation – cardiology and cancer (tumour) therapy • Localized dielectric heating (shortwave diathermy) – physiotherapy.

What are the 4 main properties of electromagnetic waves?

Every form of electromagnetic radiation, including visible light, oscillates in a periodic fashion with peaks and valleys, and displaying a characteristic amplitude, wavelength, and frequency that defines the direction, energy, and intensity of the radiation.

What type of waves do cell phones use?

Mobile phones communicate by transmitting radio waves through a network of fixed antennas called base stations. Radiofrequency waves are electromagnetic fields, and unlike ionizing radiation such as X-rays or gamma rays, can neither break chemical bonds nor cause ionization in the human body.

What are the 7 electromagnetic waves?

The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.

Do humans have electromagnetic energy?

Our bodies naturally conduct electricity. In fact, every organ and cell in the human body has its own field. The magnetic field produces electrical currents that are weaker than you may first think. At the same time, the electromagnetic field of the brain is stronger than the heart.

What types of waves do doctors use?

Transverse Waves in Medicine You may remember the image above from a previous lesson in the module about transverse waves. Doctors and medical researchers use transverse waves and their properties in many different ways.

What are 3 examples of electromagnetic waves?

Electromagnetic waves can be split into a range of frequencies. This is known as the electromagnetic spectrum. Examples of EM waves are radio waves, microwaves, infrared waves, X-rays, gamma rays, etc.

How does a TV use electromagnetic waves?

Radio waves do more than just bring music to your radio. They also carry signals for your television and cellular phones. The antennae on your television set receive the signal, in the form of electromagnetic waves, that is broadcasted from the television station. … The signal is then sent through a cable to your house.

What is the effect of electromagnetic waves on human body?

The main effect of radiofrequency electromagnetic fields is heating of body tissues. There is no doubt that short-term exposure to very high levels of electromagnetic fields can be harmful to health.
