(a) An X-ray tube produces a continuous spectrum of radiation with its shorts wavelength end ate`0.45 Å`. What is the maximum energy of the photon in the radiation? (b) From your answer to (a) , guess what order of accelerating voltage (for electrons) is required in such a tube?

Explanation

To solve the question step by step, we will break it down into two parts as given in the question.

### Part (a): Maximum Energy of the Photon

1. **Understanding the relationship between energy and wavelength**:
The energy \( E \) of a photon is related to its wavelength \( \lambda \) by the formula:
\[
E = \frac{hc}{\lambda}
