Moon's gravitational pull creates two tidal bulges on Earth's opposite sides. Sun's gravitational pull is 178 times stronger but creates smaller tidal bulges. Tides are not caused by Moon or Sun lifting oceans, but by varying gravitational forces
Devin Rahal recommends using volumizing products and alternating curl directions. Ryan Richman suggests using 1.25" curling iron and alternating directions. Both experts emphasize using curl-enhancing products and texturizing sprays
Sine wave is a periodic wave with trigonometric sine function shape. Represents single frequency with no harmonics in acoustics. Can be represented by amplitude, time, angular frequency, and phase
The Doppler effect describes the frequency change in waves due to observer motion. Christian Doppler first proposed it in 1842, confirmed by Buys Ballot in 1845. The effect occurs when the source moves towards or away from the observer
Sound is a vibration propagating as acoustic waves through media. Human hearing range is 20 Hz to 20 kHz. Sound travels fastest in solid atomic hydrogen at 36,000 m/s. Sound waves can be longitudinal in gases and liquids, transverse in solids
Sea salt spray absorbs natural oils in hair to create texture and waves. Hair should be damp but not soaking wet before styling. Use moisturizing shampoo or conditioner to maintain hair's natural oils
