Light
Electromagnetic Radiation does not need this in order to transmit energy through space.
What is a medium?
This is required to transmit sound energy through space.
What is a medium?
These kinds of waves require a medium to carry energy through space.
What are mechanical waves?
This is when light is taken into an object and transformed into heat or chemical energy
What is absorption?
This is high frequency, highly energetic, and dangerous radiation used to capture images of bones.
What is X-ray radiation?
3.0 x 108 m/sec
What is the speed of light?
This phenomenon occurs when sound waves travel through splits and bend as they pass through the opening.
What is diffraction?
This is the time it takes to complete one wavelength.
What is frequency?
This is the angle at which an object reflects off a surface from according to the law of reflection.
What is the angle of incidence?
OR
What is the angle it struck from?
OR
What is the angle between the normal line?
This is the name for signals that are continuous and have many different in-between values (like decimal places)
What are analog signals?
This determines the color of light.
What is frequency?
OR
What is wavelength?
This determines the loudness of the sound, or how intense it is.
What is amplitude?
In transverse waves, the matter moves _____ relative to the direction of the wave's travel.
What is perpendicular?
This is when a wave passes from one medium to another, changing speed as it does, and bending, changing its direction of travel.
What is refraction?
This is the name for signals which are binary (either on or off) and have discrete values.
What are digital signals?
The higher the frequency the ____ the wavelength.
What is shorter?
This is the kind of wave sound is.
What is longitudinal?
In longitudinal waves, the matter moves _____ relative to the direction of the wave's travel.
What is parallel?
This is the reason why sometimes light reflects off of surfaces at many different angles in many different directions.
What is a rough surface?
OR
What is diffuse reflection?
This is the reason Digital signals are MORE RELIABLE than Analog signals.
What is less interference?
OR
What is more clearly identifiable signals?
This kind of electromagnetic radiation is the highest energy and most dangerous, it is generated by nuclear reactions.
What is gamma radiation?
Reflection of sound occurs in either of these two forms.
What is reverberation and echo?
This is the property of an ocean wave that determines how much energy it is transferring. (Hint: Think of the difference between a Tsunami and a ripple in a pond)
What is the amplitude?
This is the direction light will travel when passing through a transparent object at a right angle.
What is straight?
This is the name for technology designed to reflect waves off of objects in order to detect objects at a distance, often used in submarines to scan the ocean floor, or in meteorology to analyze weather patterns like hurricanes?
What is RADAR/LiDAR (for electromagnetic radiation)
OR
What is SONAR (for sound waves)
