Why does sound travel faster than light?
Sound travels faster in steel than air because of molecules, in air molecules are apart from each other while in the steel they are more closer and tightly. And light is faster in vacuum because of it has less density than the steel. Light, by comparison, is an electromagnetic wave that does not require a medium.

The speed of light is much faster than the speed of sound in air. If you want to compare, the speed of sound in air is ~ 343 m/s and the speed of light is 3x10 10 m/s. In other words, light travels 186 thousand miles in 1 second, while sound takes almost 5 seconds to travel 1 mile. (published on 02/14/2017)

Sound waves exist as longitudinal waves. These waves travel through with the help of different mediums such as air and water. The travel speed of these waves is faster through water than through air. While talking about sound, we put our focus on how loud it is, that is, its amplitude, frequency, and intensity.

Does a wave need an external medium to propagate?
Since the wave is inside the propagated particle itself, there is no need for an external medium to propagate. The speed of light in a vacuum is the fastest speed any object can obtain. When light incident on the nerve ends of the eye is detected by the nervous system, a signal is sent to the brain with the energy of the incident photon.
Can sound travel inside a vacuum?
It can be seen obviously, that to propagate sound energy there must be a medium that is capable of creating a time varying pressure field. Thereby sound cannot travel inside a vacuum. Sound is a longitudinal wave because the pressure field causes the particles of the medium to oscillate in the direction of the energy propagation.
What determines the intensity of sound?
The amplitude of these oscillations decides the intensity of sound (how loud the sound is). It is obvious that to create a sound there must be a mechanical oscillation. Sound can be considered as a set of pressure pulses. It must be noted that sound always requires a medium to travel. There will be no sound in a vacuum.
How to understand the speed of sound?
To understand the significance of speed of sound, one must first understand sound. Sound is actually a wave. To be precise sound is a longitudinal wave. A longitudinal wave oscillates the particles so that the oscillation is parallel. The amplitude of these oscillations decides the intensity of sound (how loud the sound is).
What is the wave particle duality of matter?
This is known as the wave particle duality of matter. Every matter has this duality. As said earlier the theory of relativity suggests the relative velocity between any two objects cannot take velocities higher than the speed of light. This acts as a natural limit.

Why is the speed of light reduced?
It must be noted that speed of light can be reduced due to impedance of a media. This causes events such as refraction. The colour of the light depends on the wavelength of the wave. In the particle theory of light, the light waves come in small packets known as photons.
Which method uses astronomical objects to measure the speed of light?
These methods include Romer method, which uses astronomical objects to measure the speed. Several methods measure frequency and wavelength of several light beams separately and use them to calculate the speed of light.
Does light have a medium?
To get the idea of the speed of light, a good idea about light is essential. Light is a form of electromagnetic wave. It does not require a medium to travel. However, it is theoretically suggested and practically proved that light also has particle characteristics. This is known as the wave particle duality of matter.

Some of the forms of matter and energy that are covered in physics include electricity, radiation, atoms and heat.
What is the difference between high frequency and low frequency?
These vibrations are either high frequency or low frequency. Low frequency sound waves produce low tones while high frequency waves create high-pitched tones. When the frequency of the sound waves changes, it creates a change of pitch in the sound that is heard by the human ear.
