100
Waves in which the motion of the particles is perpendicular to the motion of the waves.
Transverse waves
100
The highness and lowness of sound.
Pitch
100
Energy transmitted through electromagnetic waves.
Radient energy
100
Describe the law of reflection.
A beam of light will reflect off of a surface at the same angle that it struck the surface.
100
Which characteristic do both transverse and longitudinal waves have?
Wavelength
200
The distance between two crests of a wave.
The wavelength
200
Human ears are sensitive to sound that ranges from approximately _____ to _____ Hz
20 to 20,000
200
Particles, or bundles of electromagnetic waves that travel in wavelike patterns at the speed of light.
Photons
200
When you look at objects through different mediums the object may appear to bend. What is this optical illusion called?
Refraction
200
What is the measure of how many waves pass a point in a given amount of time?
Frequency
300
The area of a longitudinal wave where the coils are spread apart.
Rarefaction
300
What determines the loudness or quietness of sound?
Amplitude, or size of the wave.
300
Two uses of infrared radiation
Cooking, night vision goggles, TV remote, mapping dust between stars in space, security systems, photography.
300
If you were going to start a fire with light from the sun would it be better to use a convex or concave lens? Explain
Convex lens because the light converges into a single point.
300
What causes an echo to occur?
Reflection of sound waves
400
Half the vertical distance from the trough to the crest of a wave.
Amplitude
400
When sound travels through a medium some of its energy is lost. What is this process called?
Absorption
400
This type of radiation is used for medical imaging of teeth and other body parts as well as airport security.
X-ray
400
What purpose do polarized sunglass lenses have?
They reduce the glare from sunlight
400
What is bending of light waves around a barrier called?
Diffraction
500
These types of waves require matter to transport their energy.
Mechanical waves
500
What is sonar?
When sound waves are sent through water and measured for how long they take to reflect.
500
What unit is used to measure electromagnetic energy? (hint: its abbreviation is eV)
Electron Volts
500
What is it called when two or more light waves meet or overlap?
Interference
500
A particle that travels in a wavelike pattern at the speed of light.
A photon
