Review of Waves and Light as a Wave

Reviewed fundamentals of waves:

• Transverse Waves (e.g. light waves)
• Longitudinal Waves (e.g. sound waves)
• Amplitude - A, x, y (meters - m)
• Wavelength - λ (meters - m)
• Period - T (seconds per cycle - s)
• Frequency - f (Hertz {cycles per second} - Hz)
• Angular Velocity - ω (radians per second - rad/s)
• Wave Speed - v (Meters per second - m/s)
