Two grating A and B have the same width of the ruled surface but A has greater number of lines. Giving reasons compare in two cases
(a) Intensity
(b) Width of principal maxima
(c) Dispersive power of grating
(d) Resolving Power of Grating
singularity: The center of a black hole, where the curvature of spacetime is maximum. At the singularity, the gravitational tides diverge; no solid object can even theoretical
why the reflective index of cladding is lower then in core of a fiber optic?

Write a mathematical expression for refractive index of the material of a prism in terms of its angle. Is the mathematical expression true for all positions of the prism?
What is the difference between a lens and a mirror? A mirror is a reflective surface. Light passes by the glass and hits the silver backing, reflecting off of it. (The angle of
