Answer:

Explanation:

The relationship between critical angle and refractive index can be derived as –

Consider a ray of light,

Let the angle of incidence i be critical angle C.

Let the angle of refraction r=900

Refractive index of the rarer medium be μa

Refractive index of the denser medium be μb

Applying Snells Law

sinisinr=μaμb

⇒μbsinC=μasin900

⇒μbμa=1sinC

Thus, we arrive at formula expressing the critical angle and refractive index relation –

μab=1sinC

Hope you understood the relation and conversion between Critical Angle and Refractive Index in Optics.
