Adhesion and cohesion are both attractive forces which mainly take place in liquids.( THIER SIMILIARITY)
Adhesion is a force of attraction between molecules of different substances while cohesion is a force of attraction between molecules of the same substances. ( THIER DIFFERENCE)
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
