What is the electromagnetic spectrum?

• The colors of the rainbow and/or prism, visible to the human eye.

• The variance of wavelengths between infrared and ultraviolet rays.

• The complete range of electromagnetic waves placed in order of increasing frequency.

• The variance of wavelengths between x-rays and gamma rays

What does radar stand for?

• Radio detection and ranging.

• Radio diffraction action rarefaction.

• Really awesome device all revere.

How are speed, wavelength and frequency related?

• Wavelength = Frequency + Speed

• Speed = Wavelength + Frequency

• Speed = Wavelength - Frequency

• Speed = Wavelength x Frequency
