| Question | Answer |
|---|---|
| Waves | Transfer Energy |
| Disturbances | Caused by forces and cause waves |
| Transverse | Type of wave where disturbance and wave move at 90 degrees |
| Longitudinal | Type of wave where disturbance and wave travel in the same direction |
| EM wave | A disturbance in the Electric and Magnetic Fields |
| Mechanical Wave | A disturbance in a medium |
| Crest | The top of a wave |
| Trough | The bottom of a wave |
| Wavelength | Distance from crest to crest, trough to trough or two similar points on a wave |
| Amplitude | Maximum distance matter moves from the rest point in a wave |
| Frequency | The number of waves that pass a given point in a given amt of time |
| Reflection | Bouncing back of a wave |
| Refraction | Bending of a wave through a different medium |
| Diffraction | Spreading out of a wave through openings or around a barrier |
| Interference | The combining of two waves |
| Constructive Interference | Meet crest to crest and trough to trough |
| Destructive Interference | Meet crest to trough and trough to crest |
| Medium | Matter through which a Mechanical wave moves |
| Inner Ear | Contains the cochlea and send impulses to the Brain via Auditory N. |
| Outer Ear | Responsible for gathering sound waves |
| Middle Ear | Amplifies sound waves |
| EM Spectrum | The range of frequencies of EM waves |
| Absorption | The transfer of energy into an object |
| Transmission | The passing of energy through a medium |
| Translucent | A soft white light bulb |
| Transparent | Clear, Colorless Scotch Tape |
| Opaque | Wooden Shudders on a house |
| Lens | Focuses the image |
| Retina | Contains Rods and Cones Cells |
| Rods | Detects black and white |
| Cones | Detects Color |
| Cornea | Responsible for most refraction as light enters |
| Revolution | 365 days for the earth and 27.5 days for the moon |
| Rotation | spinning of a body in one place |
| Axis | the plane on which a celestial body spins on, 23 degrees for the Earth |
| Solar Eclipse | Sun, Moon, Earth |
| Lunar Eclipse | Sun, Earth, Moon |
| Tides | caused by gravitational pull |
| Waning | shrinking |
| Waxing | growing |
| Waning Gibbous | 1st phase after full moon |
| Waning Crescent | last phase before new moon |
| Full Moon | We see the most part of the moon in this phase |
| New Moon | The phase just before the moon begins to wax |
| Waxing Gibbous | The phase directly after First Quarter |
| Waxing Crescent | The phase just before First Quarter |
| First Quarter | The second phase after new moon |
| Third Quarter | The 4th phase after First Quarter |
| Law of Reflection | The angle at which a wave hits a surface is equal to the angle at which it bounces off of the surface |
