INote for OP
+solved @user1 @user2...
Splease use name of topic in title
まOk
Syou know fermet's principle @まvis_hあ
S?
まYeah
Sso whats the issue?
まFinding the length
N"kinematics snell's law problem" is a hell of a title
Slol yeah
まOk
Si think min deviation vali condition se ho jana chahiye
Nhang on i think i might have it
Nyes
Nthe ray inside the prism is parallel to the base so the incident angle is whatever causes minimum deviation
if you have the incident angle, you also have the emergent angle since i=e when the ray is parallel to base
and you can use the incident angle to do some trigonometry and get the distance of point A to the prism (same as point B to the prism)

Nonce you have how much distance the light ray has travelled via trigonometry and stuff
Nyou know the speed of light in air (c)
Nand the speed of light in glass (c / refractive index)
Nyou have A to the prism, and prism to B
Nyou need how much distance the light has actually travelled in the prism now
まOk
Nmujhe neend aa rhi kuch na kuch geometry kar lo
Nmil jaana chahiye
まThanks
