From the graph of angle of deviation versus angle of incidence for an equilateral prism, the refractive index of material of prism is

The critical angle for a monochromatic light going from medium A to medium B is \(\theta\). If the speed of light in medium A is V, then the speed of light in medium B is

The incorrect statement about refractive index for a pair of media is

Consider a glass slab which is silvered at one side and the other side is transparent, given the refractive index of the class slab to be 1.5 if a Ray of light is incident at an angle at 45 degree on the transparent side the deviation of the ray of life from its initial path when comes out of the slab is

A slit of width 'a' is illuminated by red light of wavelength $6500 ?$. If the first diffraction minimum falls at $30 ?$, then the value of ' $a$ ' is
