Wavelength, Frequency, Amplitude
The lower the wavelength, the higher the frequency, and the higher the energy
What describes the relationship between wavelength and frequency?
The type of wave that does NOT require a medium
What are electromagnetic waves?
the angle of reflection is always equal to the angle of incidence
What is the Law of Reflection?
solid, liquid, or gas (material or substance)
What is a medium?
An increase or decrease in the frequency of sound, light, or other waves as the source and observer move toward(or away from) each other
What is the Doppler Effect?
Loudness is determined by...
What is Amplitude?
The type of wave that DOEs require a medium
What are mechanical waves?
The change of direction of a wave when it passes from one medium to another
What is refraction?
What material does sound travel fastest in? OR What material does light travel slowest in?
An ambulance passing you, echocardiodiagram, A car with music on passing you
Examples of Doppler effect
Pitch is determined by...
What is Frequency?
Examples of Mechanical waves
The bending of waves around a barrier
What is diffraction?
Vacuum
Where does light travel fastest? OR What can sound NOT travel through?
What is the highest point of a wave called?
Crest
Inversely proportional
What word(s) can be used to describe the relationship between wavelength and frequency?
Longitudinal
What type of wave is sound?
Constructive interference/greater amplitude
What will happen when two crests and/or two troughs line up?
Sound relies on other particles to transfer/transmit its vibrational energy
Why does sound require a medium?
What is the lowest point of a wave called?
Trough
The higher the wave length the lower the..
What is Energy?
Gamma rays
Which electromagnetic wave has the highest frequency?
What does diffraction depend on?
Wavelength and the size of the barrier/opening
The more particles get in the way of light
Why does light travel slower in more dense objects?
What is frequency measured in?
Hertz or (Hz)
