2. This is carried by a wave.

3. What is energy?

4. Label the following on the wave shown. * wavelength * compression * rarefaction * amplitude

5. Wavelength Compression Rarefaction Amplitude

6. When a wave passes from one medium into another and bends, it is called this.

7. What is refraction?

8. In this type of wave the particles of the medium move parallel to the direction of the wave.

9. What is a longitudinal wave?

10. In this type of wave the particles of the medium move perpendicular to the direction of the wave.

11. What is a transverse wave?

12. This type of wave requires a medium.

13. What is a mechanical wave?

14. When a wave bounces back from a surface it is called this.

15. What is reflection?

16. When a wave bends around an object, it is called this.

17. What is diffraction?

18. When the wavelength of a wave increases, the frequency does this.

19. What is decrease?

20. speed = wavelength * frequency This is the frequency of a wave that travels at a rate of 170 m/s and has a wavelength of 4 m.

21. What is 42.4 Hz?

22. Sound is caused when objects do this.

23. What is vibrate?

24. This part of the wave increases when the loudness of a sound increases.

25. What is amplitude?

26. This type of frequency produces a high pitched sound.

27. What is high frequency?

28. An echo results from this type of wave interaction.

29. What is reflection?

30. When a siren comes towards you, the pitch becomes higher because of this.

31. What is the Doppler effect?

32. Our eyes see a blue t-shirt as blue because this color light is reflected.

33. What is blue?

34. This color of light results when the light colors red, blue and green are mixed.

35. What is white?

36. The colors of light are different because this is different for each color.

37. What is wavelength?

38. Draw a diagram that shows how light is reflected and state the rule for reflection.

39. Rule: Angle in equals angle out.

40. ) The figure that shows the correct reflection below is ____. Figure A Figure B

41. Figure B

42. This part of the electromagnetic spectrum has the most energy.

43. What are gamma or cosmic rays?

44. This color in the visible spectrum has the least energy.

45. What is red?

46. What is wrong with the following statement? “Sound travels in transverse waves.”

47. Sound travels in longitudinal waves.

48. Why does sound travel faster through a solid and slower in a gas?

49. The particles in a solid are more tightly packed than the particles in a gas.

50. Why is it impossible to hear sound in space?

51. Sound is a longitudinal wave and requires a medium to transfer energy.
