Electromagnetic Wave


The electromagnetic spectrum 16. These rays have the shortest wavelength of all. They are emitted by some radioactive substances. They are often used in radiotherapy to kill cancer cells. gamma rays ultraviolet infrared microwaves 17. Waves with a high frequency have a _________ wavelength long short 18. The longer the wavelength the _______ the frequency lower higher 19. Electromagnetic waves are ________ waves. happy noisy transverse longitudinal 20. In __________ waves the vibrations are at right angles to the direction of the wave. longitudinal transverse 21. In __________ waves the vibrations are in the same direction as the direction of the wave. longitudinal transverse 22. Electromagnetic waves can travel through a vacuum. true false 23.
