How long would it take a radio wave of frequency `6xx10^(3) sec^(-1)` to travel from mars to the earth, a distance of `8xx10^(7)km` ?

Text Solution

Verified by Experts

The correct Answer is:
`2.66xx10^(2)sec`
Distance to be travelled from mars to earth `=8xx10^(7-)km`
`because` Velocity `= 3xx10^(8) m//sec`
`therefore` Time `=D//V=(8xx10^(10))/(3xx10^(8))=2.66xx10^(2)`sec.
