What is the de-Broglie wavelength of the $$\alpha$$- particle accelerated through a potential difference $$V$$

The kinetic energy of electron and proton is $$10^{-32}\ J$$. Then the relation between their de-Broglie wavelength is 

If a photon has velocity $$c$$ and frequency $$v$$, then which of the following represents its wavelength

The de-Broglie wavelength of a neutron at $$27^oC$$ is $$\lambda$$. What will be its wavelength at $$927^oC$$

For moving ball of cricket, the correct statement about de-Broglie wavelength is 

The mass of the electron varies with

The de-Broglie wavelength is proportional to 

When yellow light is incident on a surface, no electrons are emitted while green light can emit. If red light is incident on the surface then

de-Broglie wavelength of a body of mass $$m$$ and kinetic energy $$E$$ is given by 

A proton and an $$\alpha$$ particle are acclerated through a potential difference of $$100\ V$$. The ratio of the wavelength associated with the proton to that associated with an $$\alpha$$- particle is
