An electron beam on hitting a ZnS screen produces a scintillation on it. What do you conclude ?

Explanation

To address the question, "An electron beam on hitting a ZnS screen produces a scintillation on it. What do you conclude?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Scintillation**:
- Scintillation refers to the light flashes produced when certain materials are excited by radiation. In this case, the ZnS (zinc sulfide) screen emits light when it is struck by an electron beam.

2. **Interaction of Electrons with ZnS**:
