ALL EM waves travel at  

• different speeds
• the speed of sound
• the speed of light
• the speed of a vacuum

Infrared rays are important for

• Warming the Earth
• Providing visible light for plants
• Taking X-rays

EM waves have the same speed but different:

• frequency & medium 
• wavelength & frequency
• medium & wavelength
• color & medium
