Waves

Question 1

1. crest
2. trough
3. Amplitude
4. wavelength
5. frequency

Answer 1

1-the highest point or peak of the wave.
2-the lowest point or valley of a wave
3-for a transverse wave is the distance between a line through the middle of a wave and a crest or trough.
4-the distance from one wave crest to the very next crest.
5-the number of waves passing a fixed point in a certain amount of time.

Question 2

1. reflection
2. refraction
3. diffraction
4. interference

Answer 2

1- the bouncing back of a wave after it strikes a barrier.
2-the bending of a wave as it enters a new medium at an angle other than 90 degrees.
3-the spreading out of waves through an opening or around the edge of an obstacle.
4-the meeting and combining of waves .

Question 3

1. Electromagnetic spectrum
2. radio waves
3. microwaves
4. visible light
5. infrared light
6. ultraviolet light
7. x-rays
8. gamma rays

Answer 3

1-the range of EM frequencies
2-are EM waves that have the longest wavelengths,the lowest frequencies, and the lowest energies
3-EM waves with shorter wavelengths, higher frequencies, and higher energy than other radio waves.
4-is the part of EM spectrum that human eyes can see.
5-part of the spectrum consists of EM frequencies between microwaves and visible light.
6-part of the EM spectrum consists of frequencies above those of visible light and partially below those x-rays.
7-the opposite end of the EM spectrum from radio waves
8-have frequencies from about 10 19 Hz to more than 10 24

Question 4

1. wave
2. medium
3. mechanical wave
4. transverse wave
5. longitudinal wave

Answer 4

1-a disturbance that transfers energy from one place to another.
2-any substance that a wave moves through.
3-waves that transfer energy through matter.
4-the direction in which the wave travels(perpendicular or at a right angle.
5.the direction in which the wave travels in the same direction as the disturbance.

Question 5

1. transmission
2. absorption
3. scattering
4. polarization
5. prism
6. primary colors
7. primary pigments
8. radiation

Answer 5

1-the passage of EM wave through a medium
2-the disappearance of an EM wave into the medium
3-the spreading out of light rays in all directions because particles reflect and absorb the light.
4-is a quality of light in which all of its waves vibrate in the same direction.
5-a tool that uses refraction to spread out the different wavelengths that make up light.
6-colors which can be mixed to produce all possible colors
7-you can mix them just as you mix primary colors to produce all collors
