The EM Spectrum
The distance from crest to crest of a wave
Wavelength
The part of the EM spectrum we can see
Visible Light
An object such as wood that can't be seen through
Opaque
Light will ______ off a lake on a calm sunny day
Reflect
The height of a wave from center to crest
Amplitude
The number of waves per second
Frequency
The color light with the highest energy
Purple/ Violet
An object that allows light through, but not clearly
Translucent
A lake on a cloudy, windy day is what?
Opaque
Light travels as both a wave and this particle of light.
Photon
Electromagnetic Radiation
Green light is _________ by most plants
To allow light through, as transparent objects do.
Transmit
Scatter
The reason gamma rays are more dangerous than radio waves
smaller/ higher energy
The longest form of waves on the electromagnetic spectrum
Radio Waves
The light absorbed by a white object
None
What happens to white light as it passes through a prism
Seperates/ Slows down
The process of light bending when it hits water, causing things under water to appear to be in a different location
Refraction
Something that can be changed to affect the outcome, the shutter speed on a camera for example
Variable
The speed of infrared waves
The speed of light
The color of light that slows the LEAST as it hits a prism.
Red
If we can see ourselves in the glass covering a picture, but can also see the picture itself, what two things is the glass doing to the light?
A magnifying glass can focus sunlight on a specific point, even causing fire in some cases because the light does this as it is transmitted.
Bends inwards
During sunrise and sunset the sky contains the full range of colors because the light travels through more of this, causing the light to scatter more.
The atmosphere
