Penetrating power of X-rays does not depend on

The potential difference applied to an X-ray tube is 5 kV and the current through it is 3.2 mA. Then the number of electrons striking the target per second is

For the production of characteristic K_γ X-rays, the electron transition is

If the potential difference applied across X-rays tube is V volts, then approximately minimum wavelength of the emitted X-rays will be

X-ray will travel minimum distance in

X-rays are produced by accelerating electrons by voltage V and let they stike a metal of atomic number Z. The highest frequency of X-rays produced is proportional to

Which of the following supports the wave nature of X-rays?

A particle of mass M at rest decays into two particles of masses m₁ and m₂, having non-zero velocities. The ratio of the de-Broglie wavelengths of the particles, λ₁ / λ₂ is

A photon and an electron have equal energy E. λ_photon / λ_electron is proportional to

An image of the sun is formed by a lens of focal length of 30 cm on the metal surface of a photoelectric cell and a photoelectric current I is produced. The lens forming the image is then replaced by another of the same diameter but of focal length 15 cm. The photoelectric current in this case is
