Comparing Light Waves and Sound Waves

The video tutorial compares light waves and sound waves, highlighting their differences. Light waves are electromagnetic and can travel through a vacuum, while sound waves are mechanical and require a medium. Light waves are transverse, with oscillations perpendicular to wave direction, whereas sound waves are longitudinal, with vibrations parallel to wave direction. The speed of light is much faster than sound, explaining why we see lightning before hearing thunder. Amplitude and frequency have different meanings in light and sound, relating to intensity and color for light, and volume and pitch for sound.
