When a beam of accelerated electrons hits a target , a continuous `X` - ray spectrum is emitted from the target. Which of the following wavelength is absent in `X` - ray spectrum , if the `X` - ray tube is operating at `40,000 "volts"`?A. `0.25 Å`B. `0.5 Å`C. `1.5 Å`D. `1.0 Å` |

Answer» Correct Answer - A `lambda_(min) = (12375)/(40,000) = 0.3 Å` , Hence wavelength less than `0.30 Å` is not possible . |
