MCQ (Single Correct Answer)

-1

The figure shows surface XY separating two transparent media, medium -1 and medium -2 . The lines ab and cd represent wavefronts of a light wave traveling in medium -1 and incident on X Y. The lines ef and gh represent wavefronts of the light wave in medium -2 after refraction.

IIT-JEE 2007 Paper 2 Offline Physics - Geometrical Optics Question 8 English Comprehension

The phases of the light wave at $$c, d, e$$ and $$f$$ are $$\phi_c, \phi_d, \phi_{e}$$ and $$\phi_{f}$$ respectively.

It is given that $$\phi_{c} \neq \phi_{f}$$.

$$\phi_{c}$$ cannot be equal to $$\phi_{d}$$

$$\phi_{d}$$ can be equal to $$\phi_{c}$$

$$\left(\phi_{d}-\phi_{f}\right)$$ is equal to $$\left(\phi_{c}-\phi_{e}\right)$$

$$\left(\phi_{d}-\phi_{c}\right)$$ is not equal to $$\left(\phi_{f}-\phi_{e}\right)$$
