Measuring Waves
How is the amplitude of a wave affected by the amount of energy the wave carries?
Greater the amplitude, the more energy
The high point of a transverse wave
crest
Used to see bones
X-Rays
Which frequency of visible light has the longest wavelength?
Red
Water ripples on a pond and the "wave" at a ballpark are examples of which type of wave?
What is a transverse wave?
The wavelength of a wave is measured in?
Meters
The low point of a transverse wave
Trough
Used to treat cancer
Radiation from Gamma Rays
Which frequency of visible light has the shortest wavelength?
Blue/purple
Sound waves and ultrasound waves are examples of this type of wave.
What is a longitudinal wave?
Frequency of a wave is measured in?
Hz ( Hertz)
The distance between the identical point in two waves.
Wavelength
Used by Cell Phones and Wi-Fi
Radio Waves
What part of the electromagnetic spectrum can humans see?
Visible light
A wave in which particles move parallel to the direction of travel
What is a Longitudinal wave?
How is the frequency and wavelength related?
Inversely proportional:
As wavelength increases, frequency decreases
As wavelength decrease, frequency increases
How far a wave moves vertically from its resting point
Amplitude
Used to make popcorn
Microwaves
The substance or material a wave travels through
What is a Medium?
A wave that requires a medium to travel through
Mechanical wave
What affects the speed of a wave?
the medium it is traveling through
The number of wavelengths that pass a given point per second
Frequency
Used by heat lamps
Infrared
What is infared?
A wave in which particles move at right angles (perpendicular) to the direction of travel
Transverse wave
