IT TAKES GENERALLY 8 SECONDS TO REACH THE EARTH FROM SUN
Explanation:
Light is defined as the electromagnetic radiation with wavelengths between 380 and 750 nm which is visible to the human eye. Electromagnetic radiation, such as light, is generated by changes in movement (vibration) of electrically charged particles, such as parts of ‘heated’ molecules, or electrons in atoms (both processes play a role in the glowing filament of incandescent lamps, whereas the latter occurs in fluorescent lamps).
