General Science questions for GK paper in Banks , SSC, UPSC , RAILWAYS  and State PSC Examinations.

1. When light bends at corner the process is called Diffraction . 

2. As per to Isaac Newton the propagation of sound through gases is an example for Isothermal process

3. Sound energy is an example for Mechanical energy  .

4. The pitch of the sound wave is dependent on frequency of the sound .

5. The loudness of the sound way is dependent on intensity of the sound energy 

6. Timber or of the quality of sound is dependent on the matter with which the sound is made up of quality of the material 

7. The velocity of the sound wave increases with the increase of the density of the medium .

8. The phenomenon of echo is based on the phenomenon of the resonance .

9. The column of the stationary waves that are formed will indicate over tones .

10. The velocity of the sound wave in a medium is the product of the wave length and frequency of the vibrating medium 

11. Minimum distance required to form echo = 17.2 meters 

12. Quality of the sound is dependent of the frequency and loudness .

13. Irregular vibrations at regular intervals is called noise .

14. Regular vibrations at regular intervals is called music which is directly proportional to frequency

15. Amplitude is directly proportional to frequence

16. Number of vibrations made per second called frequency 

17. The artificial induction of vibrations in to a body at rest is called forced vibrations

18. The maximum limit of vibrating body , irrespective of force exacted  that is called natural frequency 

19. When a sound wave propagating through gases it is independent of the pressure ( pressure as got very least effect ) 

20. The propagation of sound in night times is more clear than in day time this is due to density of air .
