Light and Light Waves

Light

• energy electromagnetic, radiation

• low energy, red is lowest

• light we can see

• reflects visible light

light moves as....

• a straight path, transverse waves

• number of waves per second

• light bounces off

• light bends

wavelength

• distance: Crest ----> crest, trough ---> trough

• high energy, violet is highest

• energy, electromagnetic radiation

• light bounces off

light travels FAST

• 186,000 miles per second

• a straight path, transverse waves

• light we can see

• adsorbs all visible light

frequency

• number of waves per second

• a straight path, transverse waves

• reflects visible light (heat)

• light bends

high frequency =

• high energy, violet is highest

• low energy, red is lowest

• number of waves per second

• light bounces off

low frequency =

• lower energy, Red is lowest

• high energy, Violet is highest

• absorbs all visible light

• energy, electromagnetic radiation

visible light

• light we can see

• light bounces off

• number of waves per second

• reflects visible lights

Electromagnetic Spectrums

• ROYGBV (longest wavelength to shortest)

• number of waves per second

• light bounces off

• light bends

Black

• absorbs all visible lights (heat)

• number of waves per second

• high energy, violet is the highest

• light bends
