Critical angle--
The angle with normal at which the incident ray from denser medium after refraction will make a 90 degree refracted angle with normal in rarer medium.
Formulae:
©=sin-1(α/β)
Where
©= critical angle
α=refractive index of rarer medium
β=refractive index od denser medium
Thankyou anurag sir😊😊

[@NotAnuragMishra1]

when any incident ray come to the surface and refract and become to the parallel to the surface after reflection then that time incident angle is formed is called critical angle ❤

Very cool

[@parthjain3077]

the angle at which the light rays travel from denser medium to rarer medium making angle 90 degree with the axis is known as critical angle
