A 600 W mercury lamp emits monochromatic radiation of. wave length  331.3 nm x $${ 10 }^{ -34 }$$$$l=5,v=3x{ 10 }^{ 5 }{ ms }^{ -1 }$$)

In the following diagram if $$\mathrm { V } _ { 2 } > \mathrm { V } _ { 1 }$$ then $$-$$

The velocity of an electron in the ground state of hydrogen atom is $$2.2\times 10^{6}m/s$$. The De-Broglie wavelength associated with a muon in the ground state of a muonic hydrogen will be -$$(m\mu =207 m_{e}   , h = 6.62 \times 10^{-34}Js)$$

During an $$'\alpha '$$ particle decay from a nuclei at rest of atomic mass 284, the wavelength of the wave associated with the $$'\alpha '$$ particle is $$'\lambda '$$. Then the wavelength of the wave associated with the daughter nuclei must be

An electron is continuously accelerated in a vacuum tube by applying a potential difference. If the De Broglie's wavelength is decrease by $$10 \%$$ the change in the kinetic energy of the electron is nearly

A plane polarized monochromatic EM wave is traveling in vacuum along z-direction such that at $$t=t_{1}$$ it is found that the electric field is zero at a spatial point $$z_{1}$$. The next zero that occurs in its neighborhood is at $$z_{2}$$. The frequency(in Hz) of the electromagnetic wave is :

If the de-Broglie wavelengths associated with a proton and an $$\alpha$$-particle are equal, then the ratio of velocities of the proton and the a-particle will be:   

Calculate the momentum of a particle which has a de-broglie $$\lambda$$ of $$2.5 \times 10^{-10} \mathrm{m} $$.

If $$\lambda$$ the de-Broglie wavelength of a thermal neutron at $$27^0C$$. The wavelength of the same neutron at $$927^0C$$ is:

A proton moves on a circular path of radius $$6.6\times { 10 }^{ -3 }$$m in a perpendicular magnetic field of $$0.625$$ tesla. The De broglie wavlength associated with the proton will be:
