Vocab 1
The transfer of energy into a medium.
What is Absorption?
The amount of matter in a given space or volume.
What is Density?
Sound caused by the reflection of sound waves off a surface traveling back to the listener.
What is an Echo?
The material through which a wave travels.
What is a Medium?
EM waves with wavelengths longer than ultraviolet waves, but shorter than infrared waves.
What is Visible Light?
Waves of energy that provide us with the visible light spectrum (the colors we see).
What are Light Waves?
When a wave encounters an object in its path and bends around it.
What is Diffraction?
Waves of energy made by vibrations; require a medium (air, water, or solids) to travel.
Oscillations of electromagnetic fields that carry energy through a medium or through a vacuum.
What are Electromagnetic Waves?
The material through which a wave travels.
What is a Medium?
What is Reflection?
The rate of change of position (or distance traveled) with respect to time.
What is Speed?
What is Refraction?
A rhythmic disturbance that moves through a medium or a vacuum.
What is a Wave?
Waves of energy made by vibrations; require a medium (air, water, or solids) to travel.
What are Sound Waves?
A lens having at least one surface curved like the inner surface of a sphere.
What is a Concave Lens?
A lens with a surface that curves outward like the outer surface of a sphere.
What is a Convex Lens?
An instrument for viewing or detecting distant objects.
What is a Telescope?
A scientific tool used to greatly enlarge the image of small objects.
What is a Microscope?
What is a Hand Lens?
A clear piece of curved glass or plastic that bends passing light to focus or spread the light rays.
What is a Lens?
Device with a handle and a piece of glass or plastic that is used to make objects appear larger.
What is a Hand Lens?
Energy waves bending (changing direction and speed) as they pass from one type of object to another.
What is Refraction?
A clear piece of curved glass or plastic that bends passing light to focus or spread the light rays.
What is a Lens?
A transparent piece of glass, usually with triangular ends, used for separating white light passed through it into a spectrum or for reflecting beams of light.
What is a Prism?
