Electromagnetic Radiation IPC Notes Electromagnetic Radiation

EM Radiation EM Radiation consists of transverse waves produced by the motion of electrically charged particles. There are 7 types of EM Radiation.

EM Radiation Radio waves – EM radiation with the lowest energy 2. Microwaves – used to heat food Infrared waves – produced by anything hot; infrared rays are not visible

EM Radiation Visible light – the only part of the EM Spectrum that we can see, ROY G BIV – red, orange, yellow, green, blue, indigo & violet

EM Radiation Ultraviolet radiation – higher frequency than visible light; can’t be seen. Our bodies need UV light to produce Vitamin D, but overexposure kills healthy skin cells. The ozone layer protects us from UV light.

EM Radiation X-rays – have a very high frequency and energy; X-rays have a great penetrating power Gamma rays – have the highest frequency and energy; used in cancer treatments
