The intensity of radiative field (light source) is proportional to the square of the amplitude,so it decreases as I xas you move away from the source (this is why distant sources ofR2light are dimmer, and why sound volume decreases with distance from the source). Knowingthe power P emitted by the point source, determine the intensity I at a distance R(remember I = ).

While sailing in the ocean a sailor sees a lighthouse, but doesn’t know how far away it is. The sailor anchors their boat and measures the inten- sity of the light. They then lift their achor and sail 500 m closer to the lighthouse, noting that the intensity is now double their previous mea- surement. Given that the lamp in the lighthouse remains at a constant power and is far enough away to be considered a point source, calculate how far the lighthouse is from the sailor’s initial position.
A point source emits electromagnetic energy at a rate of (9.93x10^1) Joules per second. What is the intensity of the electromagnetic radiation (9.8070x10^0) m from the source? Express your result with three significant figures in mW/m2. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: x10 Answer Hide hint for Question 1 Calculate the wave intensity at the specified distance.
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.

(a) To appreciate the human ear’s twelve order of magnitude (1012) span from barely audible to the pain threshold, consider the following. Suppose an equivalently dynamic instrument were designed to measure distances. Taking the lower limit of the instrument to be 1.00 mm, what would be the largest distance measurable? (b) To provide a perspective for the human ear’s frequency sensitivity range (audible frequency extremes differ by 103 ), consider a speedometer with a similar speed range. If the speedometer’s maximum speed reading is 90.0 mi/h, what is the smallest finite speed that it could register?
