Rapid back and forth motion that can occur in a solid, liquid, or gas.
What is vibration?
A reflected sound wave.
What is an echo?
Electromagnetic radiation that you can see.
What is light?
Material lets NO light through.
What is opaque?
Bouncing of a wave off a surface.
What is reflection?
A longitudinal wave, caused by vibration, that can only travel through matter.
What is sound wave?
The process that is used to locate an object by using reflected sounds
Any instrument used to produce or control light.
What are optical devices?
Material lets ALL light through.
What is tranparent?
Material through which a wave passes.
What is a medium?
What happens to volume of a sound when amplitude lessens?
The study of how sound interacts with structures.
What is acoustics?
Object that can be seen because it produces its own light.
What is luminous?
Material lets MOST light through.
What is translucent?
When waves pass through an object.
What is transmission?
A unit used to measure the intensity (loudness) of a sound.
What is a decibel?
What happens to pitch when frequency increases?
It gets higher
Object can be seen because it REFLECTS light.
What is illuminated?
What is refraction?
When a wave is reflected from a surface, the angle of reflection is equal to the angle of incidence.
What is the Law of Reflection?
The change of pitch when a sound source is moving in relation to an observer.
What is the Doppler Effect?
What is reverberation?
A mirror that curves inward.
A lens that is thicker at the edges and thinner in the middle.
What is concave?
What is absorption?
