NEET 2023 Phase 1 · PhysicsPhoton energyPrevious Year Question
The minimum wavelength of X-rays produced by an electron accelerated through a potential difference of V volts is proportional to:
Answer: (B) 1/V. Answer: (b) 1/V Solution: All kinetic energy of the electron converts to one photon: eV = hc/λ_min.
- A.V
- B.1/V✓
- C.1/√V
- D.√V
Correct Answer
(B) 1/V
Solution & Explanation
Answer: (b) 1/V Solution: All kinetic energy of the electron converts to one photon: eV = hc/λ_min. λ_min = hc/(eV) ⇒ λ_min ∝ 1/V.

Energy of photon Choose the correct answer from the options given below:PhysThe number of photons per second on an average emitted by the source of monochromatic light of wavelength 600 nm, when it delivers the power of 3.3 × 10⁻³ W will be: (h = 6.6 × 10⁻³⁴ J·s)PhysElectrons of mass m with de Broglie wavelength λ fall on the target in an X-ray tube. The cutoff wavelength (λ₀) of the emitted X-ray is:PhysAn electric dipole with dipole moment 5 × 10⁻⁶ C·m is aligned with the direction of a uniform electric field of magnitude 4 × 10⁵ N/C. The dipole is then rotated through an angle of 60° with respect to the electric field. The change in the potential energy of the dipole is:PhysTwo identical charged conducting spheres A and B have their centres separated by a certain distance. Charge on each sphere is q and the force of repulsion between them is F. A third identical uncharged conducting sphere is brought in contact with sphere A first and then with B and finally removed from both. New force of repulsion between spheres A and B (radii negligible vs separation, treated as point charges) is best given as:PhysThe plates of a parallel plate capacitor are separated by d. Two slabs of different dielectric constant K1 and K2 with thickness 3d/8 and d/2 respectively are inserted in the capacitor. Due to this, the capacitance becomes two times larger than when there is nothing between the plates. If K1/K2 = 1.25, the value of K1 is:PhysA sphere of radius R is carved out of a uniform solid sphere of radius 2R (internally tangent, so its centre is at distance R from the big centre). The ratio of the moment of inertia of the small sphere to that of the remaining part, both about the Y-axis through the big sphere's centre, is:PhysThe Sun rotates once in 27 days. If it expanded to twice its present radius (uniform-density sphere, no external influence), its new period would be about:
