Waves
How much energy a sound wave has; its height
What is amplitude?
This happens when light bounces off a substance
What is reflection?
Sounds travels the fastest through this matter
What is a solid?
Caused by something vibrating
What is sound?
Highness or lowness of a sound
What is pitch?
The greater the amplitude, the louder or softer the sound
What is louder?
A prism causing a rainbow is an example of this
What is refraction?
Sound travels the slowest through this type of matter
What is a gas?
Can travel through a vacuum
What is light?
The amount of energy in a sound wave
What is amplitude?
Distance of a wave when it is measured from one peak to the next
What is wavelength?
Term which describes the passing of light entirely through a medium, such as glass
What is transparent?
Matter which is best at absorbing sound
What are soft materials, or solids, like a sponge, foam, cushion, curtains?
A form of energy
What are light and sound?
The traveling, or sending, of sound/light
What is transmission?
The shorter the wavelength, the higher or lower the frequency
What is higher?
Term in which light rays can pass through, but can stop going in a straight line and scatter in many directions, such as wax paper
What is translucent?
An example of what you can do to raise the pitch for a stringed instrument
What is tightening a string or making the string shorter?
Needs a medium to travel through
What is sound?
A material in which light/sound is transmitted
What is a medium?
The lowest point of a wavelength
What is a trough?
Light rays that cannot pass through and where a shadow is formed on the other side of the object, such as a book
What is opaque?
A reflected sound that can be heard
What is an echo?
Travels at the fastest speed possible
What is light?
To take in, like a sponge
What is absorption?
