Any wave has two directions: the up and down direction (primary wave) and the side to side direction (secondary wave).
Refraction and diffraction are two words that describe the bending of a wave. Refraction occurs when a wave changes direction as it passes from one medium to another, while diffraction is the bending of a wave around obstacles or through openings.
To find the wavelength, the following formula applies: λ = ν / f That in common words is: Wavelength = Wave's Speed / Wave's Frequency So, Wavelength of sound wave = Speed of sound wave / Frequency of sound wave Now, Speed of sound wave is 343 m/s, so Wavelength of sound wave = 343 m/s / Frequency of sound wave Frequency of sound waves audible to a human ear range between 20 Hz to 20 kHz. So filling the desired sound frequency in the equation above you get the desired wavelength of that sound wave.
secondary waves or otherwise known as s-waves
Crest of a second wave. In other words, the two crests, first wave and second wave, add up together, which is constructive.

The next type of seismic wave to arrive after the P-wave is the S-wave.
Two plural words ending in '-s':table > tableschair > chairs
Both, first the P wave Then the S wave.
Wavelength (m)=Wave speed (m/s) /Frequency (Hz)
a siesmic wave is a wave that travels through the earth. there are two MAIN types, P and S waves. a siesmograph shows the type of wave and how far away it is from that point.
