A particle of energy E₀ traveling in a region in which the potential energy is zero is incident on a potential barrier of height U₀ = 0.4E₀.The probability that the particle will be reflected is

Question

Quizplus · Accepted Answer

The probability of reflection for a particle incident on a potential barrier is given by:
R = ((V0 - E)/(V0 + E))^2
Where V0 is the height of the potential barrier and E is the energy of the incident particle.

Plugging in the given values: 
R = ((0.4 - 1)/(0.4 + 1))^2 = 0.0161 = 1.61%

Therefore, the best choice is (C).
