Question

how manny times taken by sun rays to reach at earth​

Answer 1

Answer:

Earth is at a distance of 150 million km (Approximately) or 150×109150×109 m

Speed of light is 3×1083×108 m/s

Hence time required for light to reach from sun to earth is

t=xv=15×10103×108=500t=xv=15×10103×108=500 sec.

Now converting it to minute we have 50060=8.3350060=8.33 minute

Thus for light ray it takes little more than 8 minutes to reach earth surface from sun.

PLEASE NOTE: Actual distance between sun and earth us 149.59 million km and speed of light is 299.8 millions m / s or 0.299 million km/s

Thus taking the ratio we get 500.3 seconds which is 8.3 minues OR 8 minutes and 20 seconds
