X-rays are produced in an X-ray tube operating at a given accelerating voltage. The wavelength of the continuous X-rays has values from (JEE 1998) a. 0 to ∞\infty b. λmin\lambda_{min} to ∞\infty , where λmin>0\lambda_{min} > 0 c. 0 to λmax\lambda_{max} , where λmax<∞\lambda_{max} < \infty d. λmin\lambda_{min} to λmax\lambda_{max} , where 0<λmin<λmax<∞0 < \lambda_{min} < \lambda_{max} < \infty
