Answer:
0.66c
Explanation:
Use length contraction equation:
L = L₀ √(1 − (v²/c²))
where L is the contracted length,
L₀ is the length at 0 velocity,
v is the velocity,
and c is the speed of light.
900 = 1200 √(1 − (v²/c²))
3/4 = √(1 − (v²/c²))
9/16 = 1 − (v²/c²)
v²/c² = 7/16
v = ¼√7 c
v ≈ 0.66 c
Radio waves, Middle-C, and halitosis are not forms of light.
(t) = 2t = 1.22 sec. I believe ...
Answer: A wave can be thought of as a disturbance or oscillation that travels through space-time, accompanied by a transfer of energy.
