Question

When I want is equals to 2 in a prism the angle of deviation becomes.
A. Angle of prism
B. Angle of minimum deviation
C. ANGLE OF EMERGENCE
D. ANGLE OF INCIDENCE

Answer 1

Answer:

we know that angle of deviation is

d=(i1+i2)-A

now when i1=i2

then

d=2i1-A

therefore...d(angle of deviation) becomes ..

angle of minimum deviation

i.e., d=d(min)

option (B)Angle of minimum deviation

Hope this helps you

Answer 2

Answer:

option (B)Angle of minimum deviation

Explanation:

we know that angle of deviation is

d=(i1+i2)-A

now when i1=i2

then

d=2i1-A

therefore...d(angle of deviation) becomes ..

angle of minimum deviation

i.e., d=d(min)
