Paragraph:The figure shows a surface separating two transparent media, medium-1 and medium-2. The lines and represent wavefronts of a light wave travelling in medium-1 and incident on . The lines ef and represent wavefronts of the light wave in medium-2 after refraction.
Question:Speed of light is
Options:
Answer:
B
Solution:
In medium-2 wavefront bends away from the normal after refraction. Therefore, ray of light which is perpendicular to wavefront bends towards the normal in medium-2 during refraction. So, medium-2 is denser or its speed in medium-1 is more. Hence, option (b) is correct.
