1. Sound Vs. Light

2. Type of wave: Longitudinal/ Mechanical/ compression Transverse Sound
Light
Longitudinal/
Mechanical/
compression
Transverse

3. Mediums of travel:
Sound
Light
All types solid, liquids, and gasses. Must have a medium. Closer the particles are together the faster it travels
All types solid, Liquid and gasses must be transparent. Can travel through empty space

4. Speed Slower than light waves 340m/s Faster than sound
3 X 108 m/s Or 300,000,000m/s

5. Greater amplitude give a greater volume
Sound
Light
Greater amplitude give a greater volume
High amplitude gives a brighter light

6. Higher frequency has higher pitch, lower frequency has lower pitch
Sound
Light
Higher frequency has higher pitch, lower frequency has lower pitch
Determines type of Electromagnetic radiation: frequency increases from left to right on the spectrum.

7. Larger than light waves smaller than sound waves
Wavelength

Light
Larger than light waves
smaller than sound waves

8. Can it move through a vacuum?
Sound
Light No
Yes
