Lesson 1: Wave Properties
THIS is the distance a wave travels before it is repeated.
What is "WAVELENGTH"?
When two waves overlap and build on each other, it is called THIS.
What is "CONSTRUCTIVE INTERFERENCE"?
Sound waves with a high frequency will have THIS pitch, while sound waves with a low frequency will have THIS pitch.
What are "HIGH" and "LOW"?
THESE waves allow us to see color.
What is "VISIBLE LIGHT"?
To bring out a specific color in an image, a person can apply THESE.
What are "FILTERS"?
THIS is the number of times a wave repeats in a given amount of time.
What is "FREQUENCY"?
When two waves overlap and cancel out each other, it is called THIS.
What is "DESTRUCTIVE INTERFERENCE"?
Sound waves are THESE types of waves, which need a medium (air) to travel.
What are "MECHANICAL WAVES"?
THESE waves are used for radar, measuring speeds, and heating food.
What are "MICROWAVES"?
THIS forms because light cannot pass through opaque objects.
What is a "SHADOW"?
THESE waves move in the same direction as the motion that makes them happen.
What are "LONGITUDINAL WAVES"?
When all the energy of a wave is transferred into a new material, it is called THIS.
What is "ABSORPTION"?
Sound moves fastest in THIS state of matter, and slowest in THIS state of matter.
What are "SOLIDS" and "GASES"?
THESE WAVES allow us to see thermograms (or heat signatures).
What are "INFRARED"?
The color of an opaque object is the color of the light it, THIS.
What is "REFLECTS"?
THESE waves travel in the opposite direction as the motion that makes them happen.
What are "TRANSVERSE WAVES"?
What is "REFRACTION"?
Sound is measured in THESE.
What are "DECIBELS"?
THESE waves allow us to make phone calls and use the internet.
What are "RADIO WAVES"?
You cannot see an image in choppy water because of THIS.
What is "DIFFUSE REFLECTION"?
THESE waves travel in both the direction of motion and against the direction of motion.
What are "SURFACE WAVES"?
When a wave is completely blocked from an object, but not absorbed or converted, it is called THIS.
What is "REFLECTED"?
THIS is the phenomena that explains why pitch changes as an object changes distance from a person.
What is the "DOPPLER EFFECT"?
List the entire electromagnetic spectrum, from largest wavelength to smallest.
Radio Waves, Microwaves, Infrared Rays, Visible Light, Ultraviolet, X-Rays, Gamma Rays
A mirror that is bent outwards, that makes images seem closer than they really are, are called THIS.
What is "CONVEX"?
