|
6) crest
#2: ---n--- |
the highest point of a wave
|
|
|
7) trough
#2: ---U--- |
the lowest point of a wave
|
|
|
8) wavelength
#2: --->-n--n-<--- |
the distance between one crest or trough of a wave and the next

|
|
|
22) Microwave
#5: the microwaves is very close to the radio wave on the electromagnetic spectrum |
electromagnetic waves with wavelenths that fall between those of infrred waves and radio waves
|
|
|

electromagnetic waves with the longest wavelengths, lowest frequencies and lowest energy
|
|
|
24) Absorption
#5: the color Back absorbs a lot of light that doesn't bounce off as if you were wearing purple. |
the process by which materials take in light energy
|
|
|
25) Reflection
5#The mirror reflects the light and the object in front of it off the serface of the material used to make it. |
the bouncing of a wave off a serface
|
|
|
26) Refraction
#5: when you put a pencil in a glass of water this distortion is all due to the bending of light |
the bending of light as it passes from one medium into another
|
|
|
27) Diffraction
#5: this happens when you see bars in the water and there is an opening the water moves out until go in the opening and forming back to the original state. |
the bending of waves around the barrier or the edges of an opening
|
