Question

light travels with a speed of 3*10^-8 m/s how long does the light take to reach earth from the sun?

Answer 1

hey dear here's ur answer
the speed of light is 3×10^8m/s
therefore to calculate it we will do the following steps-
we know that earth is 150×10^6km away from sun.so
• distance=v/t where v=velocity and t=time
•t=d/v= (150×10^6)/(300,000km/s)
•500s×(1min/60s)=8mins.
hope it helps
