Dual Nature of ...

A proton, a neutron, an electron and an $$\alpha$$-particle have same energy. Then their de Broglie wavelengths compare as :

Which of these particles having the same kinetic energy has the largest de Broglie wavelength?

When the velocity of an electron increases, its de Broglie wavelength:

If h is Plancks constant, the momentum of a photon of wavelength 0.01 $$A^o$$ is

A particle of mass $$4m$$ at rest decays into two particles of masses $$m$$ and $$3m$$ having non-zero velocities. The ratio of the de Broglie wavelengths of the particles 1 and 2 is:

 Find the wavelength of the incident light if the stopping potential is 0.6 V.

Relativistic corrections become necessary when the expression for the kinetic energy $$\dfrac{1}{2} mv^2$$, becomes comparable with $$mc^2$$, where m is the mass of the particle. At what de Broglie waxelength will relativistic corrections become important for an electron?

Consider the four gases hydrogen, oxygen, nitrogen and helium at the same temperature. Arrange them in the increasing order of the de Broglie wavelengths of their molecules.

Two particles $$A_1$$ and $$A_2$$ of masses $$m_1, \, m_2 \, (m_1 \, > \, m_2)$$ have the same de Broglie wavelength. Then

The de Broglie wavelength associated with a ball of mass 150 g travelling at 30 m $$s^{-1}$$ is
