(a)
location where photon is more likely to be detected?
![Check Mark](/static/check-mark.png)
Answer to Problem 1CQ
Solution: Photon is more likely to be found at x=1 m.
Explanation of Solution
Given:
Figure of probability density of photons on the x-axis
Figure.1
It is clear from the figure, that the probability of finding a particle at x=0 is 0, and the probability of finding a particle at x=1 is 2, since the probability is higher at x=1, therefore proton is more likely to be found on x=1 m
Conclusion:
Photon is more likely to be found at x=1 m.
(b)
expected number of photons in a 1 mm wide interval at x=0.50 mm

Answer to Problem 1CQ
Solution: expected number of photons in a 1 mm wide interval at x=0.50 mm is 1×103
Explanation of Solution
Given:
Figure of probability density of photons on the x-axis
Figure.1
Calculation:
It’s clear from the figure that, probability of finding photon at x=0.5 is 1
The area of curve at x=1 mm is
A=12×1×2=1×10−3 m2
The expected number of photon that can be detected in the area is
N=1×106×1×10−3=1×103
Conclusion:
Expected number of photons in a 1 mm wide interval at x=0.50 mm is 1×103

- Car A starts from rest at t = 0 and travels along a straight road with a constant acceleration of 6 ft/s^2 until it reaches a speed of 60ft/s. Afterwards it maintains the speed. Also, when t = 0, car B located 6000 ft down the road is traveling towards A at a constant speed of 80 ft/s. Determine the distance traveled by Car A when they pass each other.Write the solution using pen and draw the graph if needed.arrow_forwardIn the given circuit the charge on the plates of 1 μF capacitor, when 100 V battery is connected to the terminals A and B, will be 2 μF A 1 µF B 3 µFarrow_forwardThe velocity of a particle moves along the x-axis and is given by the equation ds/dt = 40 - 3t^2 m/s.
