Waves General
What is any disturbance that transmits energy through matter or empty space?
A wave
What wave has particles that move up and down?
A transverse Wave
What does it mean if an object is opaque?
Light does not pass through the object.
Why do we see a red apple as being the color red?
The color red is being reflected.
What type of wave does sound travel on?
Longitudinal
What type of waves require a medium to travel?
Mechanical Waves
What wave has particles that move back and forth?
A longitudinal Wave
What does it mean if an object is translucent?
Light passes through somewhat but not fully clearly
What colors have the shortest and longest wavelengths?
Shortest-Violet
Longest-Red
Which state of matter does sound travel through the fastest?
Solid
What is vibration when talking about wave particles?
Energy being passed from one particle to another.
How can we tell what type of wave a wave is?
By how its particles vibrate
What does it mean if an object is transparent?
Light passes through clearly.
What colors have the lowest and highest frequencies?
Lowest-Red
Highest-Violet
What are the areas of a sound wave where particles are closer together and further apart?
Compressions and Rarefactions
What type of waves can travel without a medium?
Electromagnetic Waves
How do you find the wavelength of a transverse wave?
Measure the distance from crest to crest
Which of the following will NOT happen when light strikes an object?
Light will disappear
What are the three primary colors of light?
Blue, Red, Green
What does frequency affect when talking about sound? What does amplitude affect when talking about sound?
What is frequency when talking about waves?
How many waves are produced in a second
How do you find the wavelength of a longitudinal/compressional wave?
What is white light made up of?
All colors of the rainbow
What are the three secondary colors of light?
Cyan, Magenta, Yellow
What is it called when an object gets louder and higher pitched as it gets closer to you but loses volume and lowers pitch as it goes away from you?
The Doppler Effect
