Given:
begin mathsize 14px style Wavelength comma space straight lambda equals 20 space cm space equals space 0.20 space straight m Wave space velocity comma space straight V equals 24 space straight m space straight s to the power of negative 1 end exponent Time space in space which space one space wave space is space produced comma space straight T equals ? straight T equals 1 over straight v Using space the space equation comma straight v equals straight V divided by straight lambda straight v equals 24 divided by 0.20 space equals space 120 space Hz straight T equals 1 over straight v equals 1 over 120 straight s equals 0.0083 space straight s space end style
