Given:
The electron is positioned in the region of width 10-12 m.
To find:
Calculate the time constant of the wave packet.
Solution:
From the given information, we have the data as follows.
The electron is positioned in the region of width 10-12 m.
The formula that relates the width and the frequency is given as follows.
λr = c
r = c/λ
r = (3 × 10^8) / (10^-12)
r = 3 × 10^20.
The time constant of the wave packet is given as follows.
T = 1/r
T = 1/(3 × 10^20)
T = 3.34 × 10^-20 s
Therefore, the time constant of the wave packet is 3.34 × 10^-20 s.
