Explanation:

The width of the plane wave front is doubled and it can be written as,

cosi

cosr

​  

=2

cos70  ∘

 

cosr  =2

r=46.84  ∘

 

The refractive index is given as,

μ=  sinr

sini

​  

 

μ=  sin46.84  ∘

sin70  ∘

μ=1.288

Thus, the refractive index in for the denser medium is 1.288.
