27 September Physics Day's Study for IIT JEE 2010

27 September Physics Wave Motion and Waves on a String – Ch.15 Session 6

Based on Text: Concepts of Physics, H C Verma, Part I

Study sections
15.11 and 15.12
15,11 Analytical treatment of vibration of a string fixed at both end.
15.12 Vibration of a string fixed at one end

y = 2A sin kx cos ωt .. (15.24)
L = n λ/2

υ₀ = v/(2L) = (1/2L) √(F/u) ….. 15(26)

y = 2Asin (nπx/L) cos ωt …(15.27)

v = (n +(1/2))(v/2L) = [(n +(1/2))/2L] √(F/u) … 15.28

Study worked out examples 6 and 7

Revise some problems in friction chapter.
