What are the importance of electronics in the advancement of technology?
An important practical contribution of electronics is the development of devices that perform various functions in systems used for the conversion and transmission of information, in control systems, in computer apparatus, and in equipment for the energy industry.
How do electromagnetic waves affect us?
At low frequencies, external electric and magnetic fields induce small circulating currents within the 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.
Who is the father of electronics?
Sir John Ambrose Fleming
What are the advantages and disadvantages of an electromagnet?
| Advantages | Disadvantages |
|---|---|
| No electrical contact problems | Have to be pulled from test surface |
| Inexpensive | No control over field strength |
| No damage to testpiece | Magnetic particles attracted to poles |
| Lightweight | Legs must have area contact |
What are examples of electronics?
Electronics is defined as devices run by electric power or the field of studying such items. An example of electronics are radios, computers, and televisions.
Who showed experimental evidence of electromagnetic waves and their link to light?
Heinrich Rudolf Hertz showed experimental evidence of electromagnetic waves and their link to light .
What is the main source of electromagnetic waves?
the sun

How electronics help in our daily life?
Literally thousands of everyday devices that we use constantly make use of electronics technology in order to operate. Equipment such as MRI, CAT and the older X-rays, tests for diabetes, cholesterol and other blood component tests all rely on electronics in order to do their work quickly and accurately.
Can electromagnetic waves make you sick?
According to the latest research, EMFs are unlikely to cause any adverse health effects. You should feel safe using your cell phone, and appliances. You should also feel safe if you live near power lines, as the EMF frequency is very low.
Where do electromagnetic waves come from?
EM waves originate from the vibration of charged particles, and unlike other waves, they can travel without a medium. The vast range of frequencies for EM waves is described by the electromagnetic spectrum. The spectrum stretches from the lowest frequency radio waves to the highest frequency gamma rays.
How can you protect yourself from harmful effects of electromagnetic waves?
5 Tips to Safeguard Against Electromagnetic Radiation
- Disable Wireless Functions. Wireless devices — including routers, printers, tablets, and laptops — all emit a Wi-Fi signal.
- Replace Wireless With Wired Devices.
- Keep EMF Sources at a Distance.
- Use Your Smartphone Safely.
- Prioritize Sleeping Areas.
What exactly are electromagnetic waves?
Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields. They are also perpendicular to the direction of the EM wave.
Why is it important to study electromagnetic waves?
The study of EM is essential to understanding the properties of light, its propagation through tissue, scattering and absorption effects, and changes in the state of polarization. Since light travels much faster than sound, detection of the reflected EM radiation is performed with interferometry.
What are electronic devices?
Definition. Electronic devices are components for controlling the flow of electrical currents for the purpose of information processing and system control. Prominent examples include transistors and diodes. Electronic devices are usually small and can be grouped together into packages called integrated circuits.
What electronics means?
1 singular in construction : a branch of physics that deals with the emission, behavior, and effects of electrons (as in electron tubes and transistors) and with electronic devices. 2 : electronic components, devices, or equipment.
What is the other term for electromagnetic waves?
Nonparticulate Radiation
Who invented electronics?
J.A. Fleming
What is the other word for experience?
Synonyms & Antonyms of experience
- chops,
- expertise,
- know-how,
- moxie,
- proficiency,
- savvy,
- skills.
What are the 4 main properties of electromagnetic waves?
It depends on their properties. Like other waves, electromagnetic waves have properties of speed, wavelength, and frequency.
How do humans use electromagnetic waves?
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 dangers of electromagnetic waves?
Possible effects of EM Radiation exposure & Hazards of Electromagnetic Radiation
- Cataracts.
- Blisters on the skin.
- Sterility and microwave auditory effect, which is hearing buzzing or microwave pulses.
How are electromagnetic waves produced?
Electromagnetic waves are created by oscillating charges (which radiate whenever accelerated) and have the same frequency as the oscillation. Since the electric and magnetic fields in most electromagnetic waves are perpendicular to the direction in which the wave moves, it is ordinarily a transverse wave.
What is the most important electromagnetic wave?
The most important of these is visible light, which enables us to see. Radio waves have the longest wavelengths of all the electromagnetic waves.
What are the advantage and disadvantage of EM waves?
Each different wavelength of light has a different color. Advantages: It is the only light that is visible to the human ey and that we can detect. Disadvantages: If there is too much exposure to visible light, it may cause blindness or eye damage. It can also hurt your retina and even damage it.
What is the importance of electronics?
Electronics is widely used in information processing, telecommunication, and signal processing. The ability of electronic devices to act as switches makes digital information-processing possible.
How do electromagnetic waves play an important role in your life?
Electromagnetic waves are used to transmit long/short/FM wavelength radio waves, and TV/telephone/wireless signals or energies. They are also responsible for transmitting energy in the form of microwaves, infrared radiation (IR), visible light (VIS), ultraviolet light (UV), X-rays, and gamma rays.
What are the advantages of electromagnetic waves?
One advantage to using an electromagnetic energy source is that, depending upon the electromechanical device used, you don’t need an external electrical source to generate electrical power. One example of this is an alternating-current (AC) generator.
