Study Notes

Light Waves

Light propagates as a transverse electromagnetic wave
Light is unique in that it can travel through a vacuum, whereas other waves require a medium to propagate

Electromagnetic Spectrum

Visible light covers a range of wavelengths between approximately 400-700 nanometers (nm) on the electromagnetic spectrum

Speed of Electromagnetic Waves

All electromagnetic waves, including light, travel at a speed of 299,792,458 meters per second (m/s) in a vacuum

Conservation Laws

The text does not mention the law of conservation of momentum
