- Šmykľavka: 1
- When you listen to the radio, watch TV, or cook dinner in a microwave oven, you are using electromagnetic waves.
- A Television with antennae.
- Šmykľavka: 2
- Radio waves, television waves, and microwaves, are all types of electromagnetic waves. they only differ fom each other in wavelength. Wave length is the distance between one wave crest to the next.
- Šmykľavka: 3
- Diagram showing the top of a wave is a crest, the bottom is a trough. Waves in the electromagnetic spectrum vary in size from very long radio waves the size of buildings, to very short gamma rays.
- Šmykľavka: 4
- A chart showing the electromagnetic spectrum. D of electromagnetic spectrum chart.
- Šmykľavka: 5
- Did you know that electromagnetic waves can not only be described by their wavelength, but also by their energy and frequency? all three of these things are related to each other mathematically.
- This means that it is correct to talk about the energy of an X-ray or the wavelength of a microwave of the frequency of a radio wave.
- Šmykľavka: 6
- The electromagnetic spectrum includes, fom longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays
- That's All Thank You!!!!
