12 flashcards · Physics · by Asmi Shekhar

1. in 1637 what did Descartes do

   corpuscular model of light

2. descartes law explains the law of

   reflection and refraction

3. wave theory of light was put forward by

   christian huygens

4. it was believed that wave requires a what to propagate

   medium

5. wave model was accepted due to

   thomas young interference in 1801

6. speed of electromagnetic wave

   c = c=1/underoot(uoEo)c = 1 / underoot (uo Eo)c=1/underoot(uoEo)

7. locus of point which are in same phase

   wavefront

8. locus of points which have same amplitude are in the same phase are

   spheres

9. speed with which wavefronts move outward from the source is called

   speed of wave

10. energy is carried in the direction perpendicular to wavefront

11. huygens principle is based on geometrical construction which allows us to determine the shape of wave front

12. each point of wavefront is source of

    secondary disturbance
