Where can electromagnetic waves be found?
Stars and lightning are natural sources of radio waves, but these are also produced by the antenna on a radio transmitter. Many sources of electromagnetic radiation come from man-made technology. On the other side of the spectrum, we have ultraviolet radiation, which is emitted by black lights and fluorescent lamps.

What is a real life example of electromagnetic waves?
Everyday life is pervaded by artificially made electromagnetic radiation: food is heated in microwave ovens, airplanes are guided by radar waves, television sets receive electromagnetic waves transmitted by broadcasting stations, and infrared waves from heaters provide warmth.
What objects have electromagnetic waves?
When you listen to the radio, watch TV, or cook dinner in a microwave oven, you are using electromagnetic waves. Radio waves, television waves, and microwaves are all types of electromagnetic waves.
Who found the electromagnetic waves?
About 150 years ago, James Clerk Maxwell, an English scientist, developed a scientific theory to explain electromagnetic waves. He noticed that electrical fields and magnetic fields can couple together to form electromagnetic waves.
What is the basic source of electromagnetic wave?
An electric dipole is a basic source of electro magnetic waves.
What are 5 examples of electromagnetic energy?
- Radio Waves.
- TV waves.
- Radar waves.
- Heat (infrared radiation)
- Ultraviolet Light (This is what causes Sunburns)
- X-rays (Just like the kind you get at the doctor’s office)
- Short waves.
What are the 5 types of electromagnetic waves?
The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.
How do electromagnetic waves work?
Electromagnetic waves are created by the vibration of an electric charge. This vibration creates a wave which has both an electric and a magnetic component. An electromagnetic wave transports its energy through a vacuum at a speed of 3.00 x 108 m/s (a speed value commonly represented by the symbol c).
What are the application of electromagnetic spectrum in our daily lives?
Electromagnetic waves have a vast range of practical everyday applications that includes such diverse uses as communication by cell phone and radio broadcasting, WiFi, cooking, vision, medical imaging, and treating cancer.
What is common among electromagnetic waves?
All electromagnetic waves have two wavefronts, which are an oscillating electric field and an oscillating magnetic field.
How many electromagnetic waves are there?
The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.
Is light an electromagnetic wave?
Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation. Electromagnetic radiation can be described in terms of a stream of mass-less particles, called photons, each traveling in a wave-like pattern at the speed of light.
