PHYSICS BOARD QUESTIONS: Do give correct answer of the 14th question."DO NOT SEND ANSWERS THROUGH LINKS"

PHYSICS BOARD QUESTIONS: Do give correct answer of the 14th question."DO NOT SEND ANSWERS THROUGH LINKS" (i) (ii) Draw a ray diagram Showing Change in the path Of the ray till it emerges from the glass slab. Name the two rays that are parallel to each Other.. Mark the lateral displacement in your diagram. 9. Why the surface Of an empty (kept in a beaker With water) Shines like a mirror,' Explain 10. A monochromatic beam of light of wavelength k passes from air into a glass block. Write an expression 10 Show the relation the speed Of light in air and the Of in II. (i) What is the cause Of refraction Of light? (iii) • 'The refractive index Of is 2.42". is meant by this 12. HOW is the index Of a material related 10 and apparent depth? 13. Draw a ray diagram to show the refraction of a monochromatic ray through a prism when it suffers minimum deviation. 14. State the dependence Of angle of deviation (i) On the refractive index of the material of the prism. (ii) On the wavelength of light 15. Name the factors affectlng critical angle for the pair ormedia.

Dear Student,

Factors on which the angle of deviation depends on are:

A) Refractive index of the prism: Because the angle of deviation is directly proportional to the angle of deviation.
B) The wavelength of the light passing through the medium: Because the angle of deviation is  Inversely proportional to the angle of deviation.
