  1. Electromagnetic Spectrum Quiz Begin Quiz

  2. Crest and trough refer to what parts of a wave? Answer

  3. The crest is the highest point and the trough is the lowest point. Next Question

  4. The distance from one point on a wave to the exact same spot on the next wave is called the ________. Answer

  5. The distance from one point on a wave to the exact same spot on the next wave is called the wavelength. Next Question

  6. As the wavelength increases the frequency _______. Answer

  7. As the wavelength increases the frequency decreases. Next Question

  8. Name the 7 types of waves in the electromagnetic spectrum. Answer

  9. microwaves, radio waves, gamma waves, visible waves, ultraviolet waves, infrared waves, x-rays Next Question

  10. Name one use for each of the seven types of electromagnetic waves. Answer

  11. microwaves - cooking food radio waves - radio and television gamma waves - medical treatments visible waves - light bulbs ultraviolet waves - suntans infrared waves - security systems x-rays - check for broken bones Next Question

  12. When you see your image in a mirror or the water of a lake, you are seeing waves being sent back to you as a ______. Answer

  13. When you see your image in a mirror or the water of a lake, you are seeing waves being sent back to you as a reflection. Next Question

  14. _______ is the bending of light rays as they move from one kind of medium to another (air to water). Answer

  15. Refraction is the bending of light rays as they move from one kind of medium to another (air to water). Next Question

  16. The bending of waves around an obstacle is called ________. Answer

  17. The bending of waves around an obstacle is called diffraction. Next Question

  18. _______ is the change in wavelength by the movement of the wave source. Next Question

  19. The Doppler Effect is the change in wavelength by the movement of the wave source. Answer

  20. A wave has a wavelength of 4 cm. Twenty waves pass a certain point in 5 seconds. What is the frequency? Answer

  21. Frequency = waves/time Frequency = 20/5 Frequency = 4 waves/sec. End Quiz
