    I was reading NCERT 11th Geography but due to lack of graphical representation there i came here(UA-cam) searching the topic and found Amit Sir's video..and this is the same content from NCERT but with a nice representation..
    Thanks for clearing the concept Amit Sir !! 🙏

    Actually when seismic or any kind of waves that travel from denser to less denser medium velocity increases .. from less denser to high denser medium , velocity decreases where as frequency remains same at both the cases with respect to magnitude .

      @randybruwet4231 2 місяці тому +1

      I get were you are coming from but. I think it’s because we are talking about the transfer of kinetic energy and not the velocity of an object, think of it like like this if you hit sand with a hammer the the energy dissipates immediately but if you hit a solid rock the energy will transfer faster through it

  • @legendvikra2352
    @legendvikra2352 3 роки тому +1

    @ 2:26 Speed of the waves is inversely proportional to the density ( meaning denser the material slower the speed ) but this speed of the waves depends on other factors too namely: Compressibility (only for P waves) and Rigidity (for both P & S waves). As Compressibility and rigidity increases towards the core the speed of the waves increases too (because both Compressibility & rigidity are directly proportional to the speed of Waves), This effect is greater than the effect caused by the increase in density therefore ultimately the Speed increases as we go deeper. Hope this was helpful. Thank you
