When white light passes through the achromatic combination of prisms, then what is observed?
(a) Deviation
(b) Dispersion
(c) Both deviation and dispersion
(d) Atmospheric refraction

Solution: When light passes through achromatic combination of prism light will internally dispersed and again recombine hence its dispersion will cancel out, but the light will go through refraction hence it will deviate from its path. hence only deviation will happen, Option A is correct.
