Waves CW 2
Across
- 1. the energy that electromagnetic waves transfer through matter or space
- 5. a wave that vibrates the medium in the same direction in which the wave travels

- 39. waves transport _______, not matter, from place to place
- 40. how much matter or mass there is in a given amount of space or volume
- 44. these waves are used to heat up food due to the specific wavelength will cause water molecules in the food to vibrate faster and heat up.

- 48. an area where the coils are spread out
- 49. an area where the coils are close together
- 51. the longer the wavelength, the __________ energy the wave has
- 52. on the same spectrum as radio waves and microwaves; it just has a shorter wavelength
- 53. the change in frequency of a wave as its source moves in relation to an observer
- 55. unit of measure to compare different levels of loudness
Down

- 9. the distance between two corresponding parts of a wave
- 10. unit of measurement for frequency that is defined as the number of waves per second
- 12. waves hitting matter and bouncing off
- 15. transverse waves vibrate __________ to the direction that the wave travels

- 35. a disturbance that travels through a medium as a longitudinal wave
- 37. the transfer of the energy of the wave to the medium it comes into contact with.
- 41. produced when two primary colors combine in equal amounts
- 42. has a wavelength that is shorter than visible light and can cause some objects to glow when molecules in those objects absorb it

- 50. waves with more energy have __________ amplitudes
- 54. a description of how high or low the sound seems
