A beam of light of frequency w is reflected from a dielectric-metal interface at normal incidence. The refractive index of the dielectric  medium is n and that of the metal is n2 = n(1+ip). If the beam is  polarized parallel to the interface, then the phase change experienced by the light upon reflection is.

Answer Strategies and trick by Manish sir (it will help you to solve it by yourself)

angle is 60

if object is placed symmetrical then images = 360/60 - 1 = 5

if unsymmetrical then 360/60 = 6
