The intensity of X-rays form a Coolidge tube is plotted against wavele

1.	The intensity of X-rays form a Coolidge tube is plotted against wavelength `lambda` as shown in the figure. The minimum wavelength found is `lambda_c` and the wavelength of the `K_(alpha)` line is `lambda_k`. As the accelerating voltage is increased (a) `lambda_k - lambda_c` increases (b) `lambda_k - lambda_c` decreases (c ) `lambda_k` increases (d) `lambda_k` decreasesA. `(lambda_(k)-lambda_(c))` increasesB. `(lambda_(k)-lambda_(c))` decreasesC. `lambda_(k)` increasesD. `lambda_(k)` decreases
Answer» Correct Answer - A As accelerating voltage is increased `lambda_(c)` decreases, `lambda_(k)` remains same, `(lambda_(k)-lambda_(c))` increases
