The speed of light is 3.0x10^5 km/sec and it takes light 1.3 seconds for light to travel from the moon to earth froim this infor
Vika [28.1K]
The motion of the light is a uniform motion with constant speed v=3 \cdot 10^5 km/s, therefore we can use the basic relationship between speed, space and time:
v= \frac{S}{t} (1)
where S is the distance covered and t is the time taken. The light takes t=1.3 s to travel from the moon to Earth, therefore by rearranging eq.(1) we can find the distance between the Moon and the Earth:
S=vt=(3 \cdot 10^5 km/s)(1.3 s)=390000 km=3.9 \cdot 10^5 km
