## anonymous 5 years ago What is the wavelength of an electromagnetic wave with frequency 300 EHz?

1. anonymous

frequency is the speed of light divide my wavelength: $f=c/\lambda$

2. anonymous

I have here that 1 EHz is $10^18$ hz

3. anonymous

and $c=300,000 km/s$

4. anonymous

speed= frequency times lembda.....for electromagnetic waves speed is the light's speed that is 299792458 m/s
