1. The radiation intensity I is defined as the average magnitude
of the Poynting vector Savg. Which is equal to Savg = I =
Erms2/cµo, where c is the speed of light. What will be the value of
Erms at the Earth's surface from solar radiation if the power per
unit area is 1,000Watts/m2?
a) 0 b) 23V/m c) 224V/m d) 614V/m e) 1,200V/m
2. calculate the valar for the BRMS magnetic field of the
wave of the previous problem
a. 2.4 microT
b. 3.7 nT
c. 7.9 pT
d. 6.8 fT
e. 0
