Welcome back! It was nice to see all of you again after the long Thanksgiving break.
Today in class we learned what the primary light colors are:
Red, Blue, and Green
We then learned a whole new vocabulary:
The big idea is that waves can only travel in one direction, and each color is composed of these waves but with different frequencies. The colors we see is known as the visible light. The visible light is a very slim piece of the electromagnetic spectrum as you can see from the picture above. To add to this, animals have adapted to see in different types of the spectrum (e.g. bees see in ultraviolet while snakes see in infrared). Humans can see in different light spectrums with the help of special glasses or computers.
Objective:
What is a primary color, and how do we see colors?
To be continued tomorrow . . .

- Wave is a disturbance that transfers energy from place to place.
- Amplitude is the height of the wave.
- Wavelength is the measurement from one point of the wave to the exact same point of the next wave.
- Crest is the top of the wave.
- Trough is the bottom of a wave.
- Frequency is the amount of given waves that pass a point in a given amount of time.
