The slope of graph drawn between stopping potential and frequency of incident light for a given surface will be:-

de-Broglie wavelength associated with an electron revolving in the $$n^{th}$$ state of hydrogen atom is directly proportional to 

The de-Brogile wavelength corresponding to the root mean square velocity of the hydrogen molecule at $$20^{o}C$$.

The equation $$E=pc$$ is valid

Electron has energy of 100 eV what will be its wavelength 

Photoelectric there should wavelength of photo sensitive material is 3700 A, the work function in eV is $$(h=6.63 \times 10^{-34} Js)$$ :

What is de-Broglie wavelength of electron having energy $$10\ keV$$?

Electrons used in an electron microscope are accelerated by a voltage of $$25$$ kV. If the voltage is increased to $$100$$ kV then the de-Broglie wavelength associated with the electrons would?

The de Broglie wavelength $$\lambda $$ associated with a  proton increases by $$25\%$$. If its momentum is decreased by $$p_0$$. The initial  momentum was:

The de-Broglie wavelength of an electron in the first Bohr orbit is
