electromagnetic waves propagate in air with speed of light
A) frequency of wave f=c/=3*10^8/(5.9*10^3)
=50847.46Hz
B)frequency of wave f=c/=3*10^8/(6*10^-6)=5*10^13Hz
C)frequency of wave f=c/=3*10^8/(5.6*10^-9)=5.357*10^16Hz
D)wavelength =c/f
=3*10^8/(6.5*10^21)=4.615*10^-14m
E)wavelength =c/f
=3*10^8/(6.5*10^21)=4.615*10^-14m
=4.615*10^-5nm
