Question 53: Dual Nature of Matter and Radiation

Question

Statement 1 :
If the accelerating potential in an X-ray tube is increased, the wavelengths of the characteristic X-rays do not change.
Statement 2 :
When an electron beam strikes the target in an X-ray tube, part of the kinetic energy is converted into X-ray energy.

Accepted Answer

Since, Potential increases
If we give the constant energy release we observe constant wavelength. So the statement 1 is true.
From Einstein equation,
$${{hc} \over \lambda } = W + K.E$$
W = work function (2.4) eV
If we given energy above 2.4 eV it will release photon.
Statement 2 is true.
Hint : ($$\lambda_{ray}$$ $$\mu$$ target material) does not depend on V$$_0$$ (accelerating potential)
Statement 1 is True
Statement 2 is True, it follows the energy conservatioin.
But statement 2 is not correct explanation of statement 1.

Answer

Statement 1 is True, Statement 2 is True, Statement 2 is a CORRECT explanation for Statement 1

Answer

Statement 1 is True, Statement 2 is True, Statement 2 is NOT a CORRECT explanation for Statement 1

Answer

Statement 1 is True, Statement 2 is False

Answer

Statement 1 is False, Statement 2 is True

Dual Nature of Matter and Radiation

Statement 1 : If the accelerating potential in an X-ray tube is increased, the wavelengths of the characteristic X-rays do not change. Statement 2 : When an electron beam strikes the target in an X-ray tube, part of the kinetic energy is converted into X-ray energy.
