A light source emits a photon during a time interval of 2.89 10-8 s. (a) Find the minimum uncertainty in the photon's energy. (b) Find the minimum frequency bandwidth of the light

Solutions

Expert Solution

We have the energy-time uncertainty relation

Where h = 6.63 x 10^-34 J-s is Planck's constant.

For the mentioned photon

(a) Therefore, the minimum uncertainty in energy should be

(b) We know that

( is frequency)

Therefore, the minimum frequency bandwidth of the light is

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...
