In the X-ray radiography technique, the tube voltage for thicker plates as compared to thin plates, should be
(A) Higher, as it gives higher wavelength
(B) Lower, as it gives higher wavelength
(C) Higher, as it gives shorter wavelength
(D) Lower, as it gives shorter wavelength
(A) Higher, as it gives higher wavelength
(B) Lower, as it gives higher wavelength
(C) Higher, as it gives shorter wavelength
(D) Lower, as it gives shorter wavelength
