An electron of mass m and a photon have same energy E. the ratio of de-Brogile wavelengths associated with them is:

SS

(c being velocity of light)

Which of the following statement about photon is incorrect?

If an electron and a photon propagate in the form of waves having the same wavelength, it implies that they have the same

Which of the following graphs correctly represents the relationship between the minimum wavelength ($\lambda$) of emitted X-rays and the accelerating potential ($V$)?

A uniform electric field and a uniform magnetic field exist in a region in the same direction. An electron is projected with a velocity pointed in the same direction. Then the electron will be

According to de Broglie, the wavelength of a particle is inversely proportional to its:

The working principle of the mass spectrograph is that for a given combination of accelerating potential and magnetic field, the ion beam (with charge $q$ and mass $M$) to be collected at different positions of ion collectors will depend upon the value of

An alpha particle (charge $2e$ and mass $4m_p$, where $m_p$ is the proton mass) is accelerated through a potential difference of $V$ volts. If its de Broglie wavelength is $0.6135 imes 10^{-3}$ nm, what is $V$?

Consider an electron $\left( {m = 9.1\,\, imes \,\,{{10}^{ - 31}}\,\,kg} \right)$ confined by electrical forces to move between two rigid walls separated by $1.0\,\, imes \,\,{10^{ - 9}}\,\,metre$, which is about five atomic diameters. The quantized energy value for the lowest stationary state is

The de-Broglie wavelength of a particle is $10^{-10}$ m. Its momentum is (h = $6.63 imes 10^{-34}$ Js):

The linear momentum of an electron, initially at rest, accelerated through a potential difference of 100 V is
