1. Waves -There are eight different forms of energy: 1. gravitational
2. electrical
3. chemical
4. nuclear
5. thermal
6. mechanical
7. sound
8. radiant/electromagnetic
-waves are a type of energy
and typically fall under the
category of mechanical,
sound, or electromagnetic energy

2. Waves -Electromagnetic waves are ultimately light
-There is a spectrum for the electromagnetism:

3. Waves

4. Waves -The spectrum is arranged by wavelength
-wavelength (symbolized as λ) is the distance between two corresponding points
-frequency (symbolized
as v) is how many
wavelengths pass a
certain point over a
given amount of time,
usually one second

5. Waves -the speed of light is c = λv
-There are 2 different kinds of waves:
1. longitudinal
2. transverse
-electromagnetic
waves are always
transverse waves

6. Waves
-atoms were seen to give off specific line emissions (specific wavelengths of light)
-these emissions are unique for each element
-electrons can behave like waves
