The star Sirius is much hotter than the sun, with a peak wavelength of 290 nm compared to the sun’s 500 nm. It is also larger, with a diameter 1.7 times that of the sun. By what factor does the energy emitted by Sirius exceed that of the sun?
A0.5 MHz antenna carried by an airplane flying over the ocean surface generates a wave that approaches the water surface in the forme
a normally incident plane wave with an electric-field amplitude of 5500 V/m. Seawater is characterized by a dielectric constant of 72,
relative permeabity of 1 and conductivity of 4 Slm. The plane is trying to communicate a message to a submarine submerged at a depth d
below the water surface.
If the submarine's receiver requires a minimum signal ampitude of 0.03 u Vim), what is the maximum depth d to which successful
communication is still possible?
Answer
If the radiant energy from the sun comes in as a plane EM wave of intensity 1340 W/m calculate
the peak values of E and B.
