1.	3Q)the absolute refractive index of water is 4/3. what is the critical angle
Answer» Answer: SINE of critical angle = 1/REFRACTIVE index EXPLANATION: so critical angle = 1/sine refractive index or = sine^-1/refractive index which is ROUGHLY EQUAL to 48degree 48.5903779°

3Q)the absolute refractive index of water is 4/3. what is the critical angle

Answer»

Answer:

SINE of critical angle = 1/REFRACTIVE index

EXPLANATION:

so critical angle = 1/sine refractive index

or = sine^-1/refractive index which is ROUGHLY EQUAL to 48degree

48.5903779°
