16. Draw the correct wave

17. RADIO WAVES longest  lowest

18. RADIO Antenna picks up the radio waves & converts it to sound waves. Each station broadcasts at a different

19. MRI (MAGNETIC RESONACE IMAGING) Uses Short wave radio waves with a magnet to create an image.

20. MICROWAVES

21. RADAR (Radio Detection and Ranging) Sends out radio waves & measures the time it takes them to return

22. Microwave ovens Waves transfer energy to the water in the food causing them to vibrate which in turn transfers energy in the form of heat to the food.
