Visible Light
Reflection example 2
A leaf appears green
Absorption example 2
A leaf captures every color wavelength except green
White light
All of the colors combined
The sky appears blue because
Blue wavelengths are smaller and reflect easier
Frequency
How often a vibration repeats itself
Transmission example
Light shines through a window
Gamma Rays
Smallest rays (smaller than atomic nuclei), make dangerous radiation
Radio Waves
Sound waves. The largest wavelength (lowest frequency) constantly around us
Transmission example 2
Sunglasses can dim sunlight, but it still passes through the lens
Ultraviolet Rays
Sunlight
The color you see
The color that is reflected back to your eyes
Wavelength.
The distance between waves.
Amplitude
The maximum height of a wave from rest
Electromagnetic Spectrum
The range of wavelengths in the electromagnetic field... From huge radio waves to tiny gamma rays
Visible Light
The range of wavelengths that includes the colors we see.
The color black
When all light is absorbed and nothing reflects back to your eyes
Absorption
When electromagnetic waves of light are captured by an object
Refraction
When light bends because it moves differently through one medium/object than another
Reflection
When light bounces off of an object
Transmission
When light passes through an object
The color white
When no light is absorbed so all of the colors reflect back to your eyes
Refraction example 2
Your feet look big and wavy underwater
Different temperatures light waves are
different colors
Lower amplitude waves mean the light has
less energy and dull colors
Longer wavelength lights mean the light has
lower frequency and warmer colors
Higher amplitude waves mean the light has
more energy and brighter colors
