Ok thanks
You are welcome
what's the critical angle???
and thanks for the solution
What is a critical angle
??
R.I = 1/sin C ; 4/3= 1/sinC; sinC=3/4; C= sin inverse 3/4; C = 48.59°
critical angle is 48.59°
What is a critical angle, please define...
when a ray of light travels from a denser to rarer medium, the incident angle at which the refracted angle is 90° i.e. it passes along the interface and doesn't escape out. The angle of incidence is the Critical angle
