    Ans 1 ->
    seperate the terms of E equation use trignometry..wwe will get two light waveswhich have maximum frequency .select that wave for calculating ke max use that frequency

  10. Two particles of same mass moving in mutually perpendicular directions and have debroglies wave length lambda 1 and lambda 2 with respect to initial frame of reference.Find the debroglies wave length of each particle with respect to centre of masss.
    10 years ago by mukhtar
    Ans 1 ->
    You can first find the momentum of each particle using p =h/(lambda) and then their speeds v1 and v2 by using p/m.... now calculate the velocity of centre of mass of the two particles using relation v(cm)=(m1v1 i +m2v2 j)/(m1 + m2) now calculate the relative velocity of each particle in frame of their cm using v1-v(cm) and v2 - v(cm) now calculate debroglie wavelength in frame of cm as lambda = h/mv(rel)
