Suppose the maximum safe average intensity of microwaves for human exposure is taken to be 1.00 W/m2. If a radar unit leaks 10.0 W of microwaves (other than those sent by its antenna) uniformly in all directions, how far away, ?min, must you be to be exposed to an average intensity considered to be safe? Assume that the power spreads uniformly over the area of a sphere with no complications from absorption or reflection. ?min= m What is the maximum electric field strength ?0 at this distance? The permittivity of free space is ?0=8.854×10−12 C2/(N·m2). The speed of light is ?=3.00×108 m/s. ?0= V/m Note: Early radar units leaked more than modern ones do. This caused identifiable health problems, such as cataracts, for people who worked near them.
In Young's experiment, the electric fields of the waves arriving at point P are given by E1 = (5.00 µN/C) sin{(4.74 × 1015)t} E2 = (9.00 µN/C) sin{(4.74 × 1015)t + 21.1 rad}, where time t is in seconds. What is the amplitude of the resultant electric field at point P?

A politician holds a press conference that is televised live. The sound picked up by the microphone of a TV news network is broadcast via electromagnetic waves and heard by a television viewer. This viewer is seated 2.3 m from his television set. A reporter at the press conference is located 4.2 m from the politician, and the sound of the words travels directly from the celebrity's mouth, through the air, and into the reporter's ears. The reporter hears the words exactly at the same instant that the television viewer hears them. Using a value of 343 m/s for the speed of sound, determine the maximum distance between the television set and the politician. Ignore the small distance between the politician and the microphone. In addition, assume that the only delay between what the microphone picks up and the sound being emitted by the television set is that due to the travel time of the electromagnetic waves used by the network.
You have decided to increase the detection range of your iphone14 with a highgain, directional parabolic dish antenna to be able to access more distant cell towers (somewhat more difficult to get into your pocket or purse, however). A 3m-diameter parabolic dish is readily available commercially, and the desired sinusoidal radio signal specification is for Emax = 0.10 µV/m. Assume the antenna absorbs all the radiation that is captured by the dish (100% efficiency): (a) What is the amplitude of the magnetic field in this signal? (b) What is the intensity, I, of the radiation received by the antenna? (c) What is the power received by the antenna?
