If the short wavelength limit of the continuous spectrum coming out of a coolidge tube is 10 A ˚ , then the debroglie wavelength of the electrons reaching the target metal in the coolidge tube is approximately :

V = 10 12400 = 1240 V λ d B = 1240 12.27 A ˚ ≈ 0.35 A ˚ ≈ 0.3 A ˚ .

If the short wavelength limit of the continuous spectrum coming out of a coolidge tube is $10 \overset{˚}{A}$ , then the debroglie wavelength of the electrons reaching the target metal in the coolidge tube is approximately :

Options:

Answer:

Solution:

$V = \frac{12400}{10} = 1240 V$

$λ_{d B} = \frac{12.27}{1240} \overset{˚}{A} \approx 0.35 \overset{˚}{A} \approx 0.3 \overset{˚}{A} .$
