b. What is the wavelength of radiation that has a frequency of 5.69 1014 s-1
c. What distance does electromagnetic radiation travel in 53.9 s?What is the frequency of radiation that has a wavelength of 0.940 碌m?
a)frequency =wavelength* speed of light
=0.94*10^(-6)*3*10^8 sec-1
b)wavelength=frequency/speed of light
c)in 1 sec electromagnetic radiation travels 3*10^8 mts
hence in 53.9 s sec electromagnetic radiation travels 3*10^8 *53.9 mts
