For which ray of light incident on 3 different media with angle of incidence 60 for all and angle of refraction is 50,45 and 40 respectively willthes 3 media show identical behaviour?

No, the three media will not show identical behavoiur. The velocity of light will be different in all the three mediums.
From Snell's Law n1 sin i = n2 sin r
For same value of angle of incidence n 2 sin r=constant
refractive index of that medium is greater whose angle of refraction is smaller.
C= speed of light in air
V= speed of light in medium
hence medium with angle of refraction 400 will have minimum velocity.
