Explanation / Answer

Part a

Frequency is given by velocity/wavelength

Part b

Speed=3*10^8 m/s

Wavelength=537 Nm=537*10^-9 m

Frequency=speed/wavelength=3*10^8/(537*10^-9) =5.59*10^14 Hz

Part c

Time period=1/frequency=1/(5.59*10^14)=1.79*10^-15 second

Time taken to make 3 cycles=3*1.79*10^-15 =5.37*10^-15 second
