PHXII11:DUAL NATURE OF RADIATION AND MATTER

357901 The ratio of de-Broglie wavelengths of molecules of hydrogen and helium which are at temperature \(27^\circ C\) and \(127^\circ C\) respectively is

1 1
2 \(\sqrt {\frac{8}{3}} \)
3 \(\sqrt{\dfrac{3}{8}}\)
4 \(\dfrac{1}{2}\)
PHXII11:DUAL NATURE OF RADIATION AND MATTER

357902 Assertion :
A wave is a moving, dynamic disturbance of matter or energy in an organised and periodic way.
Reason :
Light is defined as the electro magnetic wave within the section of the electromagnetic spectrum.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
PHXII11:DUAL NATURE OF RADIATION AND MATTER

357903 Electron beam used in an electron microscope, when accelerated by a voltage of \(20\,kV\), has a de-Broglie wavelength of \(\lambda_{0}\). If the voltage is increased to \(40\,kV\), then the de-Broglie wavelength associated with the electron beam would be

1 \(3 \lambda_{0}\)
2 \(9 \lambda_{0}\)
3 \(\dfrac{\lambda_{0}}{\sqrt{2}}\)
4 \(\dfrac{\lambda_{0}}{2}\)
