+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.Oh I remember doing this one.
In this you have to: Find the radius of curvature and use refraction by spherical surface or lens maker formula
Yesss
I remember doing this too
Pythagoras theorem
You should also find refractive index using μ= c/speedinmedium
Find R2 like this
