why reflection coefficient R=1 in step potential though there happens transmission also as a negative exponential when E<V0

The reflection coefficient of a step potential is a measure of the amount of energy that is reflected back when a wave encounters a change in the medium. It is represented by the ratio of the reflected wave's amplitude to the incident wave's amplitude.
The reflection coefficient of a step potential can be calculated using the formula R = |(Z2 - Z1) / (Z2 + Z1)|, where R is the reflection coefficient, Z2 is the impedance of the second medium, and Z1 is the impedance of the first medium.
The reflection coefficient of a step potential is affected by several factors, including the difference in impedances between the two media, the angle of incidence of the wave, and the frequency of the wave.
A high reflection coefficient indicates that a large amount of energy is being reflected back when a wave encounters a change in the medium. This could be due to a large difference in impedances between the two media or a steep angle of incidence.
The reflection coefficient of a step potential plays a crucial role in determining how waves behave when they encounter a change in the medium. A high reflection coefficient can lead to significant reflections and standing waves, while a low reflection coefficient allows waves to pass through the medium with minimal reflection.
