Question

the angle of minimum deviation for prism of 60 is 30 find angle of incidence and refraction​

Answer 1

Answer:

angle of incidence =45 degree

angle of refraction = 30 degree

Explanation:

angle i = (A+ angle of min. deviation) /2

= (60+30)/2 = 45

angle of refraction = A/2 = 60/2 = 30 degree

Answer 2

Answer:

angle of incidence = angle of prism + minimum angle of deviation/2

=> 60 + 30/2 = 90/2 = 45°

angle of refraction = angle of prism /2

=>60/2 = 30°
