The short wavelength limit of continuous X-radiation emitted by an X-ray tube operating at 30 kV is 0.414 A. Calculate Planck's constant.

\[\text{6}\text{.22 }\!\!\times\!\!\text{ 1}{{\text{0}}^{\text{-34}}}\text{erg-sec}\]

\[\text{6}\text{.624 }\!\!\times\!\!\text{ 1}{{\text{0}}^{\text{-24}}}\text{erg-sec}\]

\[\text{6}\text{.624 }\!\!\times\!\!\text{ 1}{{\text{0}}^{\text{-27}}}\text{J-sec}\]

\[\text{6}\text{.624 }\!\!\times\!\!\text{ 1}{{\text{0}}^{\text{-34}}}\text{J-sec}\]
