What is the speed of light in a vacuum?
3 x 10 ^ 8
Waves that do not require a medium are called ?
What electromagnetic waves are used for cooking and communications ?
Why might a paper appear blue ?
Blue light is being reflected

Fergie singing off key at the national anthem is an example of what ?
Sound waves travel fastest through solids. Explain why this occurs. Use the words matter, particles, and transfer in your answer.
Energy transfers from particle to particle. The closer together particles are in matter the faster energy is transferred. Solids particles are the closest together.
Equation for wavelength
Wave speed / frequency
Equation for wave speed
wave speed = frequency x wavelength
