Question | Answer |
Light | A form of energy |
Wavelength | The distance from the top of one wave to the top of the next wave |
Visible light | Colors |
Prism | Separates white color into the colors that make it up (rainbow) |
Spectrum | a range of light waves with different wavelengths and energies |
Visible spectrum | 7 colors of light that make up white light |
Shadow | places where light is blocked |
Reflection | when light bounces off an object |
The law of reflection | Incoming angle = outgoing angle |
Refraction | The bending of light as it passes from one material into another |
Transparent | (Glass, water, light plastic) allow light to pass through |
Lenses | Tools that refract light |
Convex lens | fat in the middle, magnifies, gathers light rays |
Concave lens | skinny in the middle, makes smaller, spreads light rays |
Vibration | a back and forth motion that causes sound |
Energy | what is needed to start an object's vibration |
Echo | when sound waves bounce off of surfaces |
frequency | the number of times a sound source vibrates in one second |
pitch | the highness or lowness of a sound, determined by frequency |
amplitude | the energy of a sound wave |
