Intro to Waves
Waves carry this
Energy
This is the highest part of a transverse wave
crest
The distance between the water level at rest and the crest is what?
amplitude
The bouncing back of an object or a wave when it hits a surface through which it cannot pass.
reflection
He coined the term "diffraction."
Francesco Maria Grimaldi
A wave travels through a _______________
Medium
The lowest part of a wave.
trough
The distance between two corresponding parts of a wave.
wavelength
The bending of waves as they enter a new medium at an angle.
refraction
A disturbance that transfers energy from place to place.
What is a wave?
Name on of the two wave types that does not need a medium to travel
Light or Radio
Name one of the four properties of waves
Amplitude, Wavelength, Frequency, and Speed
The number of complete waves that pass a given point in a certain amount of time (per second).
frequency
The bending of waves as they move around a barrier or pass through an opening.
diffraction
When light waves adhere to the surface of the glass and create an image reflection, this is called what?
Adsorption
A medium can be made up of what three states of matter?
Solid, liquid, gas
How do you calculate Frequency?
Number of waves occurrences divided by the total seconds.
Unit of measurement for frequency.
hertz (Hz)
transmission
Name the three types of materials that light can (or cannot) move through.
Transparent, Translucent, Opaque
All waves other than light and radio waves are what type of waves?
Mechanical
How do you calculate wave Speed?
Wavelength times Frequency
Waves in different mediums travel at different _____________?
Speed
When the medium is inconsistent (bumpy, rough, etc), waves do this
scatter
These are the type of waves that occur during an earthquake.
Seismic
