1. Lessons 5 & 6 Notes

2. Lesson 5 vocabulary
Prism – this object bends white light and splits it into separate colors
Refract – the bending of light (like through a prism)
Visible spectrum – the colors we see when white light is split

3. Lesson 5
White light is composed of all of the colors in the visible spectrum
A rainbow is produced when sunlight refracts through a raindrop

5. Lesson 6 vocabulary
Ultraviolet (UV) – invisible radiation from the Sun; can cause sunburn or skin cancer; wavelengths shorter than violet light
Infrared – invisible radiation with wavelengths shorter than red light

6. Lesson 6 Waves carry energy
Most electromagnetic waves are invisible – the only part of the electromagnetic spectrum we can see is the visible spectrum (light and colors)

7. What are the parts of a wave?
Crest – the highest point of a wave
Trough – the lowest point of a wave
Wavelength – the distance between two crests or two troughs
Amplitude – the height of a wave

8. Frequency
Waves with short wavelengths have high frequencies and carry more energy
