Step 1 We will find the reasonable size of the electric field in a beam of bright light. At the speed of light, only a small fraction of a joule is contained in a meter-length beam. The momentum of the beam is a very small fraction of a kg. m/s. Light is described by energy and momentum but possesses no mass. Step 2 We will use the equation relating the intensity of light to the wave amplitude. From the definition of intensity, we can find the energy content of the beam of light. Then the relationship between momentum, energy, and the speed of light will give us the momentum of a length of the beam. Step 3 The intensity of light I is given by the average magnitude of the Poynting vector. We have 2 I = S₂ avg P Tr²…arrow_forward
- Let's try a few more examples that relate power and energy. A certain high-efficiency LED light bulb has a power output of 9.20 W. That is, 9.20 J of electric energy is converted to electromagnetic (light) energy and radiated away every second. How much energy is output by the lightbulb if it is left on for a total time of 7.50 hours? In this case, we're relating power to energy change, so we simply use the relationship E t P = Here, instead of work W, we use in the equation E, which is the amount of energy output or converted in the amount of time t. From this, what do we find the total energy output in joules to be? 33120 X x Solve the above equation for the energy E in terms of power P and time t. Remember that 1 W = 1 J/s, so to find the energy in joules, convert the time to seconds first. There are 60 minutes in one hour and 60 seconds in one minute.
