Answer the following questions, which help you understand the difference between Thomson's model and Rutherford's model better. Keeping other factors fixed, it is found experimentally that for small thickness t, the number of alpha- particles scattered at moderate angles is proportional to t. What clue does this linear dependence on t provide ? |
| Answer» Solution :This suggests that scattering is PREDOMINANTLY due to a single collision increases with the NUMBER of target atoms which increases LINEARLY with the THICKNESS of the foil. | |
