WHEN A WAVE ENTERS A DENSER MEDIUM FROM A

RARER MEDIUM, ITS……….

• SPEED DECREASES

• WAVE LENGTH DECREASES

• PART OF THE WAVE IS REFLECTED

• FREQUENCY DOES NOT CHANGE

LIGHT ENTERING WATER FROM AIR

WHEN THE INCIDENT RAY IS PERPENDICULAR TO THE MEDIUM,

REFRACTION DOES NOT TAKE PLACE

WHEN i > øc, TOTAL INTERNAL REFLECTION OCCURS

CRITICAL ANGLE
