X- rays are produced in an X- rays tube operating at a given accelerating voltage . The wavelength of the contimous X- rays has values from
A
`0 to oo`
B
`lambda_(min) to oo` where `lambda_(min) gt 0`
C
` 0 to lambda_(max)` where `lambda_(mx) lt oo`
D
`lambda_(min) tolambda_(max)` where `0lt lambda_(min) lt tolambda_(max) lt oo`
Text Solution
Verified by Experts
The correct Answer is:
B
The centimkous X rays spectron is shown in figure All wavelength` gt lambda_(min)` are found where `lambda_(min) = (12400)/(V (in voltage)) Å` here V is the applied voltage
