Reference no: EM13554300

A mirror faces a cliff located some distance away. Mounted on the cliff is a second mirror, directly opposite the first mirror a distance 1,269.34 away and facing toward it. A gun is fired very close to the first mirror. The temperature on the day is 21.22 oC. How many times does the muzzle flash of the gun travel the round trip distance between the mirrors before the echo of the the gunshot is heard?
