consider a bright star in our sky. assume its distance from earth is 38.3 light-year (ly) and its power output is 4.00 * 10^28 W. about 100 times that of the sun. one light-year is the distance traveled by light through a vacuum in one year. a. find the intensity of the starlight at the earth. b. find the power of the starlight at the earth intercepts ( the radius of earth is 6.38 * 10^6 m .)
An electromagnetic wave strikes a 1.56-cm² section of wall perpendicularly. The rms value of the wave's magnetic field is determined to be 5.09 x 10-4 T. How long does it take for the wave to deliver 2270 J of energy to the wall? Number i Units Electromagnetic wave
Is it possible for an electromagnetic wave to travel through a vacuum? Explain. Yes, unlike a mechanical wave the electromagnetic wave does NOT require a medium in which to propagate.No, like a mechanical wave the electromagnetic wave requires a medium in which to propagate. There is not enough information to determine whether the wave propagates or not.
www WiFi (microwaves) waves travel 100m in the x-direction from a transmitter to a computer. The maximum electric field at the computer is 77.5mV/m and points in the z-direction. The frequency of the WiFi system is 2.4GHz. a. At the computer, the magnetic field points in what direction? b. At the computer, what is magnitude of the maximum magnetic field? c. How much power is being transmitted by the WiFi transmitter? d. wwwmm How much time does it take for waves to travel from the WiFi transmitter to the computer?

Part A You've recently read about a chemical laser that generates a 20.0-cm-diameter, 24.0 MW laser beam. One day, after physics class, you start to wonder if you could use the radiation pressure from this laser beam to launch small payloads into orbit. To see if this might be feasible, you do a quick calculation of the acceleration of a 20.0-cm- What speed would such a block have if pushed horizontally 95.0 m along a frictionless track by such a laser? Express your answer with the appropriate units. diameter, 98.0 kg, perfectly absorbing block. HA ? Value Units
An electromagnetic wave strikes a 1.22-cm² section of wall perpendicularly. The rms value of the wave's magnetic field is determined to be 4.58 × 10-4 T. How long does it take for the wave to deliver 1140 J of energy to the wall? Number i Units Electromagnetic wave
The average intensity a distance d₁ = 1.6 m from an omni-directional light bulb is l₁ = 1.3 W/m². (a) Write a symbolic expression for the intensity a distance d₂ = 2.5 m from the same bulb, in terms of ₁, d₁ and d₂, and calculate its numeric value. 1, ₂ W/m² (Don't worry about the font -- use 11 for 1.) (b) Calculate the maximum output power of the light bulb. Pmax = W
