Given,Frequency   (  f  )  =  2.45  ×      10    9    H  zSpeed of lights   (  v  )  =  3  ×      10    8    m      /    sTherefore, We  know  that,  Wavelength   (  λ  )  =      v    f      =            3      ×              10        8                    2.45      ×              10        9                =  0.1224  m   or   1.2  ×      10          −      1        mTherefore, Option (b) is the right answer

The waves used by a microwave oven to cook food have a frequency of 2.45 x 10^9 Hz. Calculate the wavelength of this type of wave. a) 7.35 xx 10^9m b)1.2 xx 10^(-1)m c).35 xx 10^(17)m d) 8.16
