Question

state two condition under which refractive is not observed even through light pases from one medium to another ​

Answer 1

Answer:

${\huge{\mathfrak{\underbrace{\green{Answer:-}}}}}$

NO CHANGE IN DIRECTION OF LIGHT RAY ON REFRACTION - RESULT

From Snell's Law, we have

n  

1

​  

sinθ  

1

​  

=n  

2

​  

sinθ  

2

​  

 

When light ray is incident normally (i.e. i=0,i.e. θ  

1

​  

=0), using Snell's law, we get, θ  

2

​  

=0. only speed changes and direction of  light remains the same.
