What waves carry
Energy
All waves equal
Energy
The highest point of a wave.
Crest
The lowest point of a wave.
Trough
The height of a wave.
Amplitude.
Which Waves can humans see
Visible light
The number of waves that pass in 1 second
Frequency
The time it takes for one wave to pass or complete a cycle.
Waves that travel perpendicular to the energy movement
Transverse
Waves that require a medium to travel through
Mechanical Waves
What are the 7 parts of the Electromagnetic Spectrum in order
Radio, Microwave, Infrared, Visible, Ultraviolet, X-Ray, Gamma Ray.
We can take picture of our bones with this type of radiation
X-rays
We can use this radiation to heat food and also is used in communications
Electromagnetic Radiation / Microwaves
It is part of the invisible radiation that comes from the sun
Ultraviolet
It is used to clean medical equipment and can be part of cancer treatment
Gamma Rays
What does ROYGBIV stand for
Red, Orange, Yellow, Green, Blue, Indigo, Violet
It is used to see in the night by detecting the heat
Infrared
We use this type of radiations to send and receive information
Radio/Cellphones
Refraction
When a ray of light strikes a flat, reflective surface such as a mirror, the ray reflects, or bounces off, in a new direction.
Reflection
What happens to frequency as wavelength increases
It decreases
What are the three examples in the EM that have the longest wavelength
Radio, Microwaves, and Infrared
A beam of white light passes through a glass prism and separates into different colors.
What causes this separation?
Each color of light has a different wavelength
A student turns up the volume on a speaker but does not change the song’s pitch.
Which property of the sound waves increases?
Amplitude
When the wavelength of a wave decreases, what happens to the wave’s frequency and energy?
Both frequency and energy increase
