Re: VITEEE Mock Papers
Ok, as you want the question paper of Vellore Institute of Technology Engineering Entrance Exam – VITEEE exam so here I am providing you. VITEEE exam question paper Question1. The Half-life of radioactive element is 8 days. The fraction left after 19 days will be: 124 062 093 031 Question2. Radar waves are sent towards a moving airplane and the reflected waves are received. When the airplane is moving towards the radar, the wavelength of the wave. Decreases Increases Remains the same Sometimes increases and decreases Question3. The output stage of a television transmitter is most likely to be a: Plate modulated class c amplifier Grid modulated class c amplifier Screen modulated class c amplifier Grid modulated class a amplifier Question4. Rising and setting sun appears to be reddish because: Diffraction sends red rays the earth at these times Scattering due to dust particles and air molecules are responsible Refraction is responsible Polarization is responsible Question5. A photo-sensitive material would emit electrons, if excited by photons beyond a threshold. to overcome the threshold, one would increase the: Voltage applied to the light source Intensity of light Wavelength of light Frequency of light Question6. Which phenomenon best supports the theory that matters has wave nature? Electron momentum Electron diffraction Photon momentum Photon diffraction Question7. The Reverse saturation of p-n diode Depends on doping concentrations Depends on the diffusion lengths of carriers Depends on the doping concentration and diffusion lengths Depends on the doping concentration, diffusion length and device temperature Question8. The resistance of a metal increases with increasing temperature because The collisions of the conducting electrons with electrons increase The collisions of the conducting electrons with the lattice consisting of the ions of the metal increase The number of the conduction electrons decrease The number of conduction electrons increase VITEEE exam question paper |
