Dual Nature of ...

The energy of a photon of light with wavelength $$5000 \overset {\circ}{A}$$ is approximately $$2.5\ eV$$. This way the energy of an X-ray photon with wavelength $$1\overset {\circ}{A}$$ would be:

When the kinetic energy of an electron is increased the wavelength of the associated wave will :

The energy of an electron of mass m moving with velocity V and de-Broglie wavelength $$\lambda$$ is __________. ('h' is Planck's constant)

If the uncertainty in the position of proton is $$\displaystyle 6\times { 10 }^{ -8 }m$$, then the minimum uncertainty in its speed will be:

Which of the following expression gives the de-Broglie relationship?

The de-Broglie wavelength of an electron moving with a velocity $$\dfrac{c}{2}$$ (where c is velocity of light in vacuum) is equal to the wavelength of a photon. The ratio of the kinetic energies of electron and photon is:

The energy that should be added to an electron to reduce its de-Broglie wavelength from $$1$$nm to $$0.5$$nm is.

Because we cannot ever know the initial conditions of groups of objects with perfect precision, the later behaviour of complex systems of objects may be almost completely unpredictable, even the wonderfully successful equations derived from Newtonian mechanics.
The previous statement describes the essence of which theory ?

From the pictured graph the value of Planck's constant can be determined to be about how much?

The energy of a photons is equal to the kinetic energy of a proton. If $$\lambda_1$$ is the de-Broglie wavelength of a proton, $$\lambda_2$$ the wavelength associated with the photon, and if the energy of the photon is E, then $$(\lambda_1/\lambda_2)$$ is proportional to:
