A light source emits a photon during a time interval of 4.87 multiply.gif 10-8 s. a) Find the minimum uncertainty in the photon's energy. b) Find the minimum frequency bandwidth of the light.

Expert Solution

The energy-time uncertainty relation is

Where is uncertainty in energy, is time interval or the uncertainty in time, and h = 6.63 x 10^-34 J.s.

Given,

So, the minimum uncertainty in photons energy is

(b) We have

where is the frequency of the photon and E is energy.

So, the minimum frequency bandwidth of the light is

In a region where the speed of sound is 330 m/s, a source of sound emits a frequency of 440Hz. Assuming the observer is not moving, at what speed would the source have to move for the observed frequency to be 330Hz? Are they moving towards or away? A. Torwards B. Away C. This situation is not possible D. The Observer is at rest Part 2: Use the setup above. Enter the speed of the source with the units of...

A monochromatic light source emits 164 W of average electromagnetic power uniformly in all directions. The speed of light is 3 � 10^8 m/s. Calculate the average electric-field energy density 4 m from the source. Answer in units of J/m3 . (uE=1/2 E0E2) Calculate the average magnetic-field energy density at the same distance from the source. uE=1/2 E0(cB)2 Find the wave intensity at this location. What is the pressure exerted by the light on a mirror located at the same...

You have a diffraction grating with 3000 lines/cm. You also have a light source that emits light at 2 different wavelengths, 428 nm and 707 nm, at the same time. The screen for your experiment is 1.5 meters from the diffraction grating. A. What is the line spacing for the grating? B. What is the difference in the angle of the 2nd bright fringe for each wavelength for this grating? C. Which wavelength is closer to the center of the...

Design an Moore FSM for an 8-interval stoplight system where the red light is ON (yellow and green lights are OFF) for 4 intervals, then yellow light is ON (red and green lights are OFF) for 1 interval and then green light is ON (red and yellow lights are OFF) for 3 intervals. After the green light has been ON for three intervals, we go back to the red light being ON for 4 intervals. Use binary encoding for states...

17. For time t on the interval [0, 8], people arrive at a venue for an outdoor concert at a rate modeled by A(t) = 0.3sin(1.9t) + 0.3cos(0.6t) + 1.3. For time t on the interval [0, 1], no one leaves the venue, but for t on the interval [1, 8], people leave the venue at a rate modeled by L(t) = 0.2cos(1.9t) + 0.2sin t + 0.8. Both functions A(t) and L(t) are measured in hundreds of people per...

A traffic light at a certain intersection is green 50% of the time,yellow 10% of the time, and red 40% of the time. A car approaches this intersection once each day. We would like to know about the number of days that pass up to and including the first time the car encounters a red light. Assume that each day represents an independent trial. a) Define the random variable of interest, it support, and parameter values. b) What is the...
