For a symmetric (equilateral) prism, the prism formula can be written as (a) 2sin (30+(δm)/(2)) (b) 2/√(3)sin (30+(δm)/(2)) (c) 2sin (60+(δm)/(2)) (d) 2/√(3)sin (60+(δm)/(2))

Answer: (a). Prism formula: μ = (sin ((A+δm)/(2)))/(/2) Equilateral prism: A = 60°, sin 30° = 1/2 μ = 2sin (30° + (δm)/(2)) So the answer is (a).

For a symmetric (equilateral) prism, the prism formula can be written as

Show answer and solution

Answer: (a)

Prism formula: $\mu = \frac{\sin\left(\frac{A+\delta_m}{2}\right)}{\sin\frac{A}{2}}$
Equilateral prism: $A = 60^\circ$ , $\sin 30^\circ = \frac{1}{2}$
$\mu = 2\sin\left(30^\circ + \frac{\delta_m}{2}\right)$
So the answer is (a).
