Question

How many minutes would it take a light wave to travel from the planet Venus to Earth? (Average distance from Venus to Earth = 28 million miles).

Answer 1

`t=2.51min`

Step-by-step explanation:

The time taken by the light to travel a given distance is defined as:

`t=(d)/(c)`

Here c is obviously the speed of light. Now we convert the average distance form Venus to Earth to meters:

`28*10^(6)mi*(1609.34)/(1mi)=4.51*10^(10)m`

Finally, we calculate the minutes taken by the light to travel from Venus to Earth:

`t=(4.51*10^(10)m)/(3*10^8(m)/(s))\\t=150.33s*(1min)/(60s)=2.51min`
