In figure a ray of light undergoes refraction from medium A to medium

1.	In figure a ray of light undergoes refraction from medium A to medium B. If the speed of light in medium A is v then the speed of light in medium B will be1. √3 v2. v / √33. 2v4. v/2
Answer» 1. √3 v \(\frac{sin\,i}{sin\,r}=\frac{v_1}{v_2}\) ⇒ \(\frac{sin\,30}{cos\,30}=\frac{v}{v'}\) ⇒ v' = √3 v

In figure a ray of light undergoes refraction from medium A to medium B. If the speed of light in medium A is v then the speed of light in medium B will be1. √3 v2. v / √33. 2v4. v/2

Answer»

1. √3 v

\(\frac{sin\,i}{sin\,r}=\frac{v_1}{v_2}\)

⇒ \(\frac{sin\,30}{cos\,30}=\frac{v}{v'}\)

⇒ v' = √3 v
