The figure shows a surface X Y separating two transparent media, medium-1 and medium-2. The lines a b and c d represent wavefronts of a light wave travelling in medium-1 and incident on X Y. The lines ef and g h represent wavefronts of the light wave in medium- 2 after refraction.
The phases of the light wave at c, d, e and f are ϕ_c, ϕ_d, ϕ_e and ϕ_f respectively. It is given that ϕ_c≠ϕ_f (2007, 4M)
(a) ϕ_c cannot be equal to ϕ_d
(b) ϕ_d can be equal to ϕ_e
(c) (ϕ_d-ϕ_f) is equal to (ϕ_c-ϕ_e)
(d) (ϕ_d-ϕ_c) is not equal to (ϕ_f-ϕ_e)
