Question

Which of the following travels slowest in air and which one fastest? Supersonic aircraft, light, sound.

Answer 1

Hint: Finding the speed of light, sound and supersonic aircraft in an ideal condition in the atmosphere where the air is medium. Explain a bit about every topic of the following, in terms of any effect. Taking all of the following speeds in meters per second and comparing them with each other.

Complete answer:
Let’s talk about light:
If light is traveling through any medium (for example, air or water), light does slow down. This slowdown is caused by the index of refraction of the medium, which is the technical term applied to how much light can bend when it enters that medium.
The speed of light is the same value as c \[=\] \[3\times {{10}^{8}}\dfrac{m}{s}\] in a vacuum no matter who measures it.
Light in the air is \[1.0003\] times slower than light in a vacuum, which slows it down. It reaches from \[299,792,458\dfrac{m}{s}\] to \[299,702,547\dfrac{m}{s}\] that's a slowdown of \[89,911\dfrac{m}{s}\], which looks like a lot but is only three ten-thousandths of the speed of light.
Let’s talk about supersonic aircraft:
Supersonic aircraft are designed for speed that exceeds the speed of sound. For objects traveling in the dry air at a temperature of \[20{{C}^{\circ }}\] at sea level, this speed is approximate \[343.2\dfrac{m}{s}\]. It creates shock waves or "sonic boom” when traveling faster than sound. Sounds are traveling as sound waves as they propagate through an elastic medium.
Let’s talk about sound:
If we consider the atmosphere in an ideal situation, then the speed of sound is about \[343\dfrac{m}{s}\]. The speed of sound is the distance traveled per unit of time by a sound wave as it propagates through an elastic medium.
In the air, sound travels longitudinally at different speeds, mostly depending on the molecular mass and temperature of the gas, and pressure has little effect.
By comparing all of the following speed in the air in the same condition, we concluded that:
Light is faster than other following objects and sound is slowest.

Note: The speed of light can be used with time of flight measurements to measure large distances to high precision. We can use the speed of sound to determine how far away a lightning strike has occurred. Other examples of sound: Sonar is used in navigation, forecasting weather, and for tracking aircraft, ships, submarines, and missiles.
