- - 20.How is impact parameter related to angle of scattering? OR

The impact parameter $\left(b\right)$ is proportional to -

$\theta$ is scattering angle.

In Rutherford scattering experiment, the correct angle of scattering of $\alpha -$ particles for impact parameter equal to zero is

In Rutherford scattering experiment for scattering angle of ${180}^{\circ }$ what will be the value of impact parameter?

In Rutherford's scattering experiment , if impact parameter is zero then angle of scatting for $\alpha$ particleis
