When 0.25$$\mathop A\limits^o $$ X-Rays strike a material, the photoelectrons from the $$K$$ shell are observed to more in a circle of radius $$23 \ma...

In an electron gun the potential difference between the filament and plate is $$4000 \mathrm{~V}$$. What will be the velocity of electron emitting fro...

An electron of mass $$m$$ and charge $$e$$ initially at rest gets accelerated by a constant field $$2 E$$. The rate of change of de-Broglie wavelength...

The stopping potential (V0) versus frequency $$\nu $$ of a graph for photoelectric effect in a metal. From the graph, the Plank's constant (h) is ...

The de-Broglie wavelength of an electron moving with a velocity $$\frac{c}{3}$$ (c = 3 $$\times$$ 108 m/s) is equal to the wavelength of photon. The r...

The potential difference applied to an X-ray tube is decreased. As a result, in the emitted radiation,

Lights of two different frequencies whose photons have energies 1.5 eV and 2.5 eV respectively illuminate a metallic surface whose work function is 0....
