Homework Statement
A 2 meter deep swimming pool is filled with water. A mirror is placed at the bottom and a small fish swims 5 cm (0.05m) below the surface. If you look at the swimming pool from above, how deep does the fish appear to be (a), and how deep does it's image appear to be (b)...
Hello!
I have two quick (hopefully) questions about dipole antennas and conductivity.
1) Two dipole antennas are placed at the points (λ/4,0,0) & (-λ/4,0,0) where λ is the wavelength of the emitted radiation. The dipole moments are:
p1 = p_ω *e^(-ωt)
p2 = p_ω *e^(-(ωt-α))
where p_ω...
