Vocabulary
What is Transparent?
Letting all the light through so objects on the other side can be seen clearly
What is Vibration?
Vibration is a back and forth motion.
What is Amplitude?
How tall or short a wave is (the distance from the crest of the wave to its midline).
Give 3 examples of a Transparent object
Air, Eyeglass lens, window
What is Translucent?
Letting only some light through so objects on the other side appear blurry
What is Volume?
Volume is the loudness or softness of a sound
Why/how does a prism create a rainbow?
It bends light into it’s component colors
Give 3 examples of a Translucent object
Stained glass, plastic lid, wax paper
What is Opaque?
Completely blocking light from passing through
What is Pitch?
Pitch is the highness or lowness of a sound as determined by its frequency
How is light refracted as it passes from one material to another?
It is bent
Give 3 examples of an Opaque object
Book, Wall, desk
What is Reflection?
Reflection is the bouncing of a wave off a surface. A mirror is an example of light reflecting.
What is Frequency?
Frequency is the number of wavelengths that pass a reference point in a given amount of time.
The incoming angle of light is always equal to the outgoing angle of light.
True or False?
True
True or False
True
Sound tends to travel with the greatest speeds in solids and the slowest in gases.
What is Refraction?
Refraction is the bending of a wave as it changes angle passing from one substance into another. A lens can refract, or bend, light as it passes through it.
What are Sound Waves?
Sound waves are waves that transfers energy through matter and spreads outward in all directions from a vibration. Sound can travel through solids, liquids and gases. Sound tends to travel with the greatest speeds in solids and the slowest in gases. The medium in which a sound wave is traveling has an effect on its speed.
The medium through which a sound wave is travels has an effect on its speed.
True or False?
True
Give an example of light reflecting
A mirror is an example of light reflecting.
