Limiting angle of a prism is defined as the largest angle of the prism (A) for which no emergent ray is obtained. (a) Find the limiting angle `(A_(0))
Limiting angle of a prism is defined as the largest angle of the prism (A) for which no emergent ray is obtained.
(a) Find the limiting angle `(A_(0))` for a glass prism having refractive index `mu`.
(b) A prism has limiting angle for light of wavelength `lambda_(0)`. Can there be any emergent ray for light of wave- length `lambda lt lambda_(0)`.
