## Ackbar Group Title What is the wavelength of an electromagnetic wave with frequency 300 EHz? 3 years ago 3 years ago

1. fauxshaux Group Title

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

2. Ackbar Group Title

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

3. fauxshaux Group Title

and $c=300,000 km/s$

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