PRESENTATION OUTLINE
DEFINITION:
the range of wavelengths or frequencies over which electromagnetic radiation extends.

FREQUENCY:
Frequency is a word used in Maths to mean "how often something happens".

With waves, it's "how many waves per second..."
THIS IS NORMALLY MEASURED IN HERTZ (HZ)

...the distance from the peak of one wave to the peak on the next wave.

BLUE LIGHT HAS HIGHER ENERGY THAN RED LIGHT
WHICH MEANS: SHORTER WAVELENGTHS AND HIGH FREQUENCY OF WAVES

WHILE RED LIGHT HAS THE LOWEST ENERGY LEVEL
WHICH MEANS: LOW WAVELENGTH FREQUENCIES AND INTENSITY

VIOLET BEATS THEM ALL ...
VIOLET HAS THE HIGHEST ENERGY AND FREQUENCY
GAMMA RAYS, X RAYS, ULTRAVIOLET RADIATION, VISIBLE LIGHT...
infrared radiation, microwaves and radio waves.

FREQUENCY TO WAVELENGTH...
THE HIGHER THE FREQUENCY MEANS THE SHORTER THE WAVELENGTHS

ENERGY TO FREQUENCY
THE MORE ENERGY A COLOR OR RAY HAS- THE MORE FREQUENT WAVES...

ENERGY TO WAVELENGTHS
MORE ENERGY=higher frequency=short more frequent wavelengths

DIRECTIONS
- Get a partner (or make a friend)
- Grab a slinky
- Go to the hall (you're not in trouble- for fun)
- Grab one end and make a wave
- Show differnt wavelengths for color and frequencies
