if the speed of a wave is 340 m/s and is frequency is 1700 Hz. then lemda for this wave in cm wil be

Wavelength = velocity / frequency

                      = 340 / 1700

                      = 1/5

                      = 0.2 m 

  • 2
Speed(v)=wavelength*frequency Speed =340m/sec Wavelength =speed /frequency Wavelength=340/1700 Wavelength =0.2cm
