Question

Light takes 8 minutes 20 seconds to reach from sun on the earth. If the whole atmosphere is
filled with water, the light will take the time (nwa= 4/3)
(a) 8 minutes 20 seconds
(b) 8 minutes
(c) 6 minutes 11 seconds
(d) 11 minutes 6 seconds​

Answer 1

Answer:

Will take 6 minutes and 11 seconds to reach the earth, Which the atmosphere is filled with water

Answer 2

Answer:

Given , nWa = 4/3

So , 4/3 = 500 seconds /time taken by light to reach the earth through water (t)

Thus , 4/3 = 500/t

Then , t = 375 seconds

So closest option is c

Hence , Answer is c

I HOPE IT'S HELPFUL !
