(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A 50cm wavelength EM wave in air has 50mW/m^2 of energy.

what is the frequency?

what is the average E field?

What is the B field strength?

What would be the λ in water?

2. Relevant equations

I found the λ. How do I find it in water

3. The attempt at a solution

E = √50/.5*ε°*c... is that correct?

frequency = 17.3 Khz
