A boy looks at the image of an object in a plane mirror. He observes two images, a main bright one and the other faint. The observed images result from
- A. reflection onlyCorrect
- B. refraction only
- C. diffraction and interference
- D. reflection and refraction
Explanation
Per the source key, this is attributed to reflection only (from the front and back mirror surfaces); some textbooks instead attribute the faint secondary image to combined reflection and refraction at the glass surface, so this is worth double-checking against your syllabus.
