Question

What is the wavelength (in meters) of an electromagnetic wave whose frequency is 2.63 × 1012 s−1?

Answer 1

To find the wavelength of an  electromagnetic wave for the given frequency can be determined by using the formulaSpeed=Wavelength x FrequencyWavelength=Speed/FrequencyGenerally Speed of the electromagnetic wave is 3x10^8 m/sBy substituting the values Wavelength=3x10^8 m/s / 2.63x10^12 s^-1Wavelength=1.14 x 10^-4 metres
