Light reaches the earth from sun in nearly:
Correct answer: C. 8 minutes - 30 sec
- A. 16 minutes
- B. 10 minutes
- C. 8 minutes - 30 sec
- D. 8 sec
Explanation
This is very close to the correct time.In reality, light from the Sun reaches Earth in a little over 8 minutes (about 8 minutes 20 seconds).Since 8 min 20 sec is not given, the closest choice is 8 min 30 sec.So option C is the correct answer.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
