Chapter 33: Q4P (page 1001)

About how far apart must you hold your hands for them to be separated by 1.0nanolightsecond(the distance light travels in1.0ns)?

Short Answer

Expert verified

One nano light second is equal to 0.30m.

Step by step solution

01

Listing the given quantities

Velocity of light, c=3×108m/s

Time periodt=1ns=1×10-9sec

02

Understanding the concepts of velocity and distance

Using the velocity of light in air, we can find the distance traveled by the light in air in the given time.

Formula:

d=c×t

03

Calculations of the distance traveled in the given time

d=c×t=3×108m/s×1×10-9s=0.30m

The distance traveled in the given time is 0.30m

During a test, a NATO surveillance radar system, operating at 12GHzat180kW of power, attempts to detect an incoming stealth aircraft at90km.Assume that the radar beam is emitted uniformly over a hemisphere. (a) What is the intensity of the beam when the beam reaches the aircraft’s location? The aircraft reflects radar waves as though it has a cross-sectional area ofonly0.22m2.(b) What is the power of the aircraft’s reflection? Assume that the beam is reflected uniformly over a hemisphere. Back at the radar site, what are (c) the intensity, (d) the maximum value of the electric field vector, and (e) the rms value of the magnetic field of the reflected radar beam?

A certain helium–neon laser emits red light in a narrow band of wavelengths centered at632.8nm and with a “wavelength width” (such as on the scale of Fig. 33-1) of0.0100nm. What is the corresponding “frequency width” for the emission?

Question: What is the radiation pressure 1.5maway from a 500wlight bulb? Assume that the surface on which the pressure is exerted faces the bulb and is perfectly absorbing and that the bulb radiates uniformly in all directions.

Question: In the Figure, light enters a 90∘triangular prism at point Pwith incident angle θ, and then some of it refracts at point Qwith an angle of refraction of 90∘.(a) What is the index of refraction of the prism in terms of θ?(b) What, numerically, is the maximum value that the index of refraction can have?(c) Does light emerge at Qif the incident angle at Pis increased slightly? and (d) Does light emerge at Qif the incident angle at Pis decreased slightly?

Figure:

In Fig. 33-40, initially unpolarized light is sent into a system of three polarizing sheets whose polarizing directions make angles of θ1=40°, θ2=20°, andθ2=40°with the direction of theyaxis. What percentage of the light’s initial intensity is transmitted by the system? (Hint: Be careful with the angles.)
