Question

plz solving this physics numerical qns 9​

Answer 1

Explanation:

I thinkk the answer can be option-a because as we kni refractive index increases then the speed of the ray of light gets decrease

Hence the answer is medium B which has more refractive index than medium A because there is more deviation in medium B than medium A

hope this helps

Sorry if any mistake

Mark brainliest if possible

Answer 2

Answer:

(a) Greater than unity

Explanation:

since light rays in medium B goes towards normal . so it has greater restrictivd index and lesser velocity of light with respect to medium A. so refractive index of medium B with respect to medium A is greater than unity
