Physics

• wave is a transfer of energy through a medium from one point to another
• longitudinal waves are parallel to the direction of travel
• transverse waves are perpendicular to the direction of travel
• wave is a disturbance or back and forth motion that travel through something like water or air carrying energy without transporting object
• when an object is vibrating (moving back and forth), it creates wave
• in water waves, the energy is transferred by water molecules
• when waves travel through solids, liquid and gases, matter is not carried along with the waves
• the types of wave: mechanical wave and electromagnetic wave
• mechanical wave requires medium to transfer energy from one place to another
• electromagnetic wave does not require any medium to carry its energy
• types of mechanical wave: longitudinal and transverse wave
• transverse wave: wave motion that is perpendicular to wave direction
• transverse wave move up and down or side to side
• mechanical wave is the wave that only travel through matter or medium
• water wave is an example of transverse wave
• sound waves are examples of longitudinal wave
• the crest and trough are the locations of the highest and lowest points of the wave
• the amplitude is the measurement of a maximum displacement
• the wave length is the distance between one complete cycle
• in the transvers wave, the distance from the crest to crest or trough to trough would be 1 wavelength
• a longitudinal wave is parallel to wave direction
• example of longitudinal wave is sound wave or the slinky wave that you push or pull
• the compression and rare faction are areas of maximum displacement
• in longitudinal wave, the distance from one compression to one compression or from one rarefaction to one rarefaction is the wavelength
• the wavelength is also called lambda
• speed or velocity of wave is the measure of how fast the wave propagates though a medium
