8 What are EM Waves? EM waves are non-mechanical waves. They do not need a medium to travel. EM waves are produced by a vibrating electric charges.

9 EM waves exist in an enormous range of frequencies. This continuous range of frequencies is known as the electromagnetic spectrum.

10 Longest Wavelength Shortest Wavelength

11 How are they different from one another? They differ from each other in wavelength. Remember: wavelength determines frequency. Higher Frequency=More energy

12 Scientist subdivide the spectrum into smaller parts mostly on the basis of how each region of EM waves interacts with matter.

13 Size of wavelength

14 USES

15 Visible Light Waves
