See them allWhat is a prism?
Answer
A prism is a homogeneous, transparent medium such as glass bounded by two plane surfaces inclined to each other at an angle. The two faces are refracting faces, the angle between them is the refractin…
What is the angle of deviation in a prism?
Answer
The angle of deviation is the angle between the incident ray produced forward and the emergent ray produced backward. For a general prism, δ = i + i′ − A, where i is angle of incidence, i′ is angle of…
Why does a prism deviate light toward its base?
Answer
Light bends toward the normal when it enters glass from air and bends away from the normal when it leaves glass into air. The combined effect makes the emergent ray deviate toward the base of the pris…
State the prism angle relation.
Answer
For refraction through a prism, r + r′ = A, where r is the angle of refraction at the first face, r′ is the angle of incidence at the second face, and A is the angle of prism.
A ray passes through a prism with i = 60°, i′ = 50°, and A = 40°. Find the deviation.
Answer
Given: i = 60°, i′ = 50°, A = 40°. Formula: δ = i + i′ − A Step 1: δ = 60° + 50° − 40° Step 2: δ = 70° Answer: δ = 70°…
What is minimum deviation in a prism?
Answer
Minimum deviation is the least value of deviation obtained for one particular angle of incidence. At minimum deviation, i = i′ and r = r′ = A/2. If the base angles of the prism are equal, the ray insi…
State the refractive index formula at minimum deviation.
Answer
n = sin[(A + δm)/2] / sin(A/2), where n is refractive index, A is the prism angle, and δm is the angle of minimum deviation. It is used to find the refractive index of prism material from A and δm.
A prism has A = 60° and minimum deviation δm = 40°. Find the refractive index.
Answer
Given: A = 60°, δm = 40°. Formula: n = sin[(A + δm)/2] / sin(A/2) Step 1: n = sin[(60° + 40°)/2] / sin(60°/2) Step 2: n = sin 50° / sin 30° Step 3: n = 0.7660 / 0.5 Step 4: n = 1.532 Answer: n = 1.532…
