Question

to reach from sun to earth light tales 8 minute. what is the order of magnitude of distance of sun to earth in km​

Answer 1

Sunlight travels at the speed of light. Photons emitted from the surface of the Sun need to travel across the vacuum of space to reach our eyes. The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth.

Answer 2

Answer:

Time t=8 min=480 sec

Speed of light c=3×10^8 ms^-1

Distance=t×c = 1.44×10^11 m = 1.44×10^8 km

So order of magnitude os distance is 10^8 km
