1.	State the totalthe total internal reflection phenomenonwith suitable diagram.
Answer» Total internal Reflection If a ray of light travelling in a denser medium STRIKES a rarer medium at an angle of INCIDENCE i which is greater than the critical angle C , it GETS totally reflected back into the same medium this phenomenon is CALLED as 'total internal reflection' Diagram is attach More Information Critical angle When a ray of light goes from denser medium to a rarer medium, the angle of refraction is greater than the angle of incidence . if the angle of incidence is increased the angle of refraction may eventually BECOME 90° The angle of incidence for which the angle of refraction is 90° is called the critical angle for that interface . it is generally Denoted by C

Answer»

Total internal Reflection

If a ray of light travelling in a denser medium STRIKES a rarer medium at an angle of INCIDENCE i which is greater than the critical angle C , it GETS totally reflected back into the same medium this phenomenon is CALLED as 'total internal reflection'

Diagram is attach

More Information

Critical angle

When a ray of light goes from denser medium to a rarer medium, the angle of refraction is greater than the angle of incidence . if the angle of incidence is increased the angle of refraction may eventually BECOME 90°

The angle of incidence for which the angle of refraction is 90° is called the critical angle for that interface . it is generally Denoted by C
