What is absorption?
True or False: Sound needs a medium to travel.
True
Light travels in a ____________ line.
What is straight?
True or False: Reflection is when heat, light, or sound bounces off something.
True
Edna Mode, "The Incredibles"
The Sun and lightbulbs are examples of what kind of light?
What is white light?
__________ is a measure of how loud or soft a sound is.
What is volume?
How does light energy travel?
What are waves?
A __________ object that light can pass through; it does not make a shadow
What is transparent?
What movie is the quote "You are a toy!" from, and who said it?
Woody, "Toy Story"
True or False: Light-colored objects/materials absorb more light energy than dark-colored ones
False - Dark colors tend to absorb more light than light colors
What is pitch?
A measure of how low or high something sounds/is related to the speed of vibrations.
Which travels faster - light or sound energy?
What is light energy?
A ______________ object that light can pass partially through; it makes a light shadow.
What is translucent?
What movie is the quote, "Hard to see the Dark Side is.", and who said it?
Yoda, "Star Wars: Episode I"
What happens when light energy has been absorbed by an object?
It changes to thermal (heat) energy/the object may feel warm or hot
Fast vibrations result in ______- pitched sounds.
Slow vibrations result in ______ - pitched sounds.
high
low
A ________ is a material through which a light wave travels.
What is a medium?
It is the change in direction as a light or sound wave enters a new medium.
What movie is the quote "I hope you're pleased with yourselves. We could all have been killed - or worse, expelled." from, and who said it?
Hermione Granger, "Harry Potter and the Sorcerer's Stone"
If an object appears blue, this means that it is reflecting which colors? Which colors are being absorbed?
It is reflecting the color blue, and it is absorbing all other colors of the light spectrum.
Describe the difference between high/low frequency.
High frequency = fewer vibrations/low pitch
Low frequency = more vibrations/high pitch
Light will travel and maintain its direction until it. . . (3 things)
What is interacts with an object or moves from one medium to another that can reflect, refract or absorb the light energy?
Describe amplitude and how it effects sound(s).
The amplitude of a sound wave is the size of its original vibration, a sound is loud or soft depending on its amplitude
Ex. How far a violin string is pulled results in a sound's amplitude (small amplitude = soft sound/large amplitude = loud sound)
What movie is the quote, "I'll get you my pretty-and your little dog too!" from, and who said it?
