Question

While deriving prism formula which of the following condition is NOT satisfied?
a) i=e
b) 1 =
c) r=A/2
d) 8 = i +e+r​

Answer 1

Answer:

answer is option d

Explanation:

option d is the correct ans.

Answer 2

The correct answer is option (d) m = i + e + r.

Explanation:

• While deriving the prism formula, the condition m = i + e + r is not satisfied.
• For a prism of a small angle, the refracted ray inside the prism becomes parallel to the base by this the angle of incidence becomes equal to the angle of emergence.
• Therefore, the first condition is satisfied.
• So, the correct answer is option d which is the condition that is nt satisfied.
