It takes about 8 minutes for light to travel from the sun to earth. pluto is 40 times as far from us as the sun when pluto is closest to earth. how long does it take light to reach earth from pluto? (b) radio waves travel at the speed of light. what problems would you have if you tried to conduct a two-way conversation between earth and a spacecraft orbiting pluto?

(a) 5 hours 20 min

(b)I would have a great inconvenience with the delay of the signal

Explanation:

Hello

To find the time it takes for light to reach Earth from Pluto, we use a rule of three

Step 1

define

distance from sun to earth=x

distance from pluto to earth=40x

Step 2

Rule of three

distance    time

x       ⇒   8 minutes

40x   ⇒   A minutes    

(a) 5 hours 20 min

Step 3

I would have a great inconvenience with the delay of the signal, since the message I send will arrive 5 hours and 20 minutes later, if the message is answered immediately I will listen to it 320 min after that, more than ten and a half hours to give and receive a hello
