Question

Compare the speed of light given as 3×10^8 m/s to the speed of sound given by 3.43×10^2 m/s.​

Answer 1

Step-by-step explanation:

c = 3 x 108 m/s. Since radio waves travel at a constant speed, the distance traveled is given by: distance = speed times time. or d = c t.

please mark as brainliest answer.

Answer 2

Answer:

The speed of light is almost eighty lakhs times greater than that of speed of sound.

Step-by-step explanation:

$\rm \: Speed \: of \: light = 3× {10}^{8} m/s \\ \\ \rm \: Speed \: of \: sound \: = \: 3.43 \times {10}^{2} \: m /s \\ \\ \\ \rm \: Ratio \: of \: speed \: of \: light \: to \: sound \: = \frac{Speed \: of \: light }{Speed \: of \: sound} \\ \\ \rm \: Ratio \: of \: speed \: of \: light \: to \: sound \: = \frac{3× {10}^{8} m/s}{3.43 \times {10}^{2}m/s } \\ \\ \rm Ratio \: of \: speed \: of \: light \: to \: sound \: = \frac{ {300,000,000 \cancel {m/s}}}{{ 343\: \cancel{m/s}}} \\ \\ \rm Ratio \: of \: speed \: of \: light \: to \: sound \: = \rm \: 874,635.56851311 \\ \\ \rm Ratio \: of \: speed \: of \: light \: to \: sound \: ≈ \rm \: 874,636 \\ \\ </p><p></p><p>$

Therefore the speed of light is almost eighty lakhs times greater than that of speed of sound.
