urgent help in physics

please help i cant understand any thing from the critical angle is there any body who can help???? please :!: :!: :!:

The least Angle of Incidence at which total internal Reflection takes place. The angle of incidence in a denser medium, at an Interface between the denser and less dense medium, at which the Light is refracted along the interface. When the critical angle is exceeded, the light is totally reflected back into the denser medium. The critical angle varies with the indices of Refraction of the two media with the relationship: sinIc = n´/n where Ic is the critical angle; n´ the Refractive Index of the less dense medium; and n the refractive index of the denser medium.

The formula for critical angle is shown where c is the critical angle, n 1 is the refractive index of the less dense medium, and n 2 is the refractive index of the denser medium.

thx man u helped alot

CRITICAL ANGLE: thant angle of incidence for which the angle of refraction is 90 degrees with the normal.......... if the angle of incidence is greater than the critical angle than the ray is totally internally reflected............... formula for CRITICAL ANGLE:1/REFLECTIVE INDEX.........
i hope u got it right man.......

If you are having difficulty with physics, perhaps you can turn to psychics. Some specialize in learning assistance and can use their gifts to shed light on complex topics and concepts. Don't hesitate to ask for help wherever you find it - sometimes unusual approaches can bring surprising results. You can contact a psychic near me. Good luck studying physics!
