Answer:
Orange
(484×10^12/s)(620×10^-9)
=30080×10^3 m/s
=3×10^8 m/s
Yellow
(517×10^12/s)(580×10^-9)
=299860×10^3 m/s
=3×10^8 m/s
Green
(566×10^12/s)(530×10^-9)
=299980×10^3 m/s
=3×10^8 m/s
Blue
(638×10^12/s)(470×10^-9)
=299860×10^3 m/s
=3×10^8 m/s
Indigo
(685×10^12/s)(445×10^-9)
=304825×10^3
=3×10^8 m/s
Violet
(744×10^12/s)(400×10^-9)
=297600×10^3 m/s
=3×10^8 m/s
Explaination:
why is the answers the same
because if the number next to ones (>2<79308) is above 5 (2>79<308) you need to plus it with 1
and if the number next to ones is not above 5
(1>43<870) you need to use the first number
=1×10^8 m/s
I hope it help =)
