Answer 1

Answer:

The sides of the Glass Slab are Parallel also normals normal drawn at two locations will be equal.

So,r=r.

Now, Refractive Index of glass with respect to the Air=1/Refractive Index of Air with respect to the Glass.

So,

Sini/Sinr=1/Sinr/Sine.

Sini/Sinr=Sine/Sinr

Sini=Sine

i=e.

Answer 2

In this imagination game, you need to connect pairs (and sometimes more) of emotions with associations. Think and find the pair of each emotion. Harder than you think!
