Question | Answer |
White light | all colors of the rainbow |
Primary colors of light | red, green, and blue |
Light | a type of wave that carries energy, no medium necessary |
Reflected | waves bounce off of surfaces |
Refracted | waves bend as they travel through different mediums |
Diffraction | waves bend around a barrier |
Opaque | material that allows no light to pass through (wall) |
Translucent | material that allows some or little light to pass through (stained glass window) |
Transparent | material that allows almost all light to pass through (regular glass window) |
ROYGBIV | color order of the visible light spectrum |
Wave | repeating disturbances or movements that carry or transfer energy through matter or space |
Matter | anything that has mass and takes up space |
Mechanical waves | waves that need matter to be able to transfer energy |
Medium | the matter that energy travels on |
Transverse/longitudinal wave | matter moves at right angles to the direction of the wave |
Compression wave | matter moves forward and backward |
Sound wave | compression waves, travel faster in solids, cannot travel in space due to the fact they need a medium |
Wavelength | the distance between one point on a wave and the identical point on the next wave |
Amplitude | the distance measured from the line of origin/rest position straight up to the crest or down to the trough. Related to the energy a wave can carry. Larger amplitude the greater the energy |
Frequency | the number of waves that pass a fixed point in one second. Measured in hertz (Hz) |
Crest | the highest point on a wave |
Trough | the lowest point on a wave |
Compression | the densely packed area of a compression wave |
Rarefaction | the less dense area of a compression wave |
Constructive interference | two waves with the same frequency overlap and form a single larger wave. |
Destructive interference | when waves of different frequencies overlap and cancel out each other. |
Intensity | the amount of energy that flows through a certain area in a specific amount of time. |
Loudness | the perception of intensity. The higher the intensity the louder the sound |
Decibels | the measure of intensity of a sound, abbreviated by dB |
Pitch | the highness or lowness of a sound, pitch depends on the frequency of the sound wave |
Ultrasonic waves | sound waves with frequencies above 20,000 Hz |
Infrasonic waves | sound waves with frequencies below 20 Hz (subsonic) |
Doppler effect | the change in frequency that occurs when the source of the sound is moving in relative to the listener |
