Question

for a prism having angle of prism 60 degree and mu =root 2 , the angle of minimum deviation is.​

Answer 1

Answer:

Minimum deviation angle =30

Explanation:

mu=sin (dm+A/2)//sin (A/2)

Root 2=sin (dm+60/2)//sin(60/2)

Root 2=sin (dm+60/2)//sin 30

Root 2 =sin (dm+60/2)//1/2

Root 2 =sin (dm +60/2)*2

Root 2/2=sin(dm +60/2)

1/root 2=sin(dm +60/2)

Sin 45=sin(dm +60 /2)

45=dm +60 /2. . . (cancel the sin)

45*2=dm+60

90=dm+60

90-60=dm

dm=30

Hope this helps you
