Hi Abhishek,

begin mathsize 12px style Wavelength comma space frequency space and space velocity space are space related space as straight v equals nλ 1 right parenthesis space No. of space waves space in space 1 space second space is space the space frequency therefore straight n equals straight v over straight lambda equals fraction numerator 24 over denominator 20 cross times 10 to the power of negative 2 end exponent end fraction equals 120 space waves space in space straight a space second 2 right parenthesis space Time space for space 1 space wave space is space time space period straight T equals 1 over straight n equals 1 over 120 equals 8.3 space ms end style
