If the angle of incidence of a ray of light falling on the glass is 30 degree and the angle of refraction is 19 degree what is the refractive index of a glass

Answers

Answered by chemistrywala

refractive index is sin of incidence / sin of refraction therefore it is equal to = sin30°/sin19° =1/2×1/0.32= 1/0.64= 100/64 appx. 1.56

Ameer03: but how u got the value of sin 19 degree

chemistrywala: i have checked it from internet

Ameer03: but what will u do in exams

Ameer03: whether they will provide it or not

chemistrywala: yes they have to provide the value because we can't remember all the values

Ameer03: hmm k. Thnk u

chemistrywala: mark my answer brainliest
