Thunder occurs at the same time as lightning, but we see the light first and then we hear the thunder. Why? Sound travels much slower than light: about 330 meters/second. It is quite fast, just over 1,000 km / h.

What is faster lightning sound light or lightning?

When the electrical discharge occurs in a storm, we can immediately see the lightning and then comes the thunder. This is because this flash travels at the speed of light (300,000 km/s), which is faster than the speed of sound (340 m/s).

What is faster than lightning?

Lightning is electricity with a power of up to 30 million volts and a temperature of up to 30,000ºC, five times hotter than the surface of the Sun. They travel at a speed of up to 115,000,000 kilometers per hour and fall on Earth more than 17 million times a day, or about 200 times a second.

What is faster thunder or light?

When the electrical discharge occurs in a storm, we can immediately see the lightning and then comes the thunder. This is because this flash travels at the speed of light (300,000 km/s), which is faster than the speed of sound (340 m/s).

What is faster than sound?

Light travels extremely fast (300,000,000 m/s). In fact, it travels faster than anything else. Sound travels very slowly.

What depends on the speed of sound?

The speed of sound in a medium depends on how quickly vibrational energy can be transferred through the medium. Therefore, the derivation of the speed of sound in a medium depends on the medium and its state.

What is the difference between lightning bolt and thunder?

So to summarize: lightning is the electrical discharge, lightning is the flash, and thunder is the noise we hear rumbling during a thunderstorm.

What is the pitch of a sound and what does it depend on?

The tone or height is the quality that allows us to distinguish between a high or high sound and a low or low sound. For a pure sound the pitch is mainly determined by the frequency, although it can also change with pressure and envelope.

What exceeds the speed of sound?

How is the sound barrier broken? The speed at which the sound barrier is broken depends on many conditions, including weather and altitude. Under ideal conditions, at room temperature, the speed of sound is 343 meters per second (1,235 kilometers per hour).

What is the speed of sound?

The speed at which sound waves are transported is represented by the letter “c” and is measured in m/s. The speed of sound at 1ºC is 331.6 m/s. If we increase the temperature, the speed increases. Therefore, the speed at 20ºC is 343 m/s, although it is usually rounded to 344 m/s.

Where is the speed of sound faster?

In general, the speed of sound is greater in solids than in liquids, and in liquids it is greater than in gases. This is due to the greater degree of cohesion that atomic or molecular bonds have the more solid the matter is.

Which wave travels faster?

And it turns out that it is tens of times higher than the already known 340 meters per second. In fact, a sound wave can travel much faster, up to 36 km per second, as long as the conditions are right.

What is the speed of light?

Since then, light has an exact speed of 299,792.458 kilometers per second. However, its speed varies depending on the environment in which it is located. For example, in space, light travels at its maximum speed.

Where is sound faster in air or in water?

In water, sounds propagate faster and with less energy loss than in air; sound and ultrasonic waves are transmitted in the sea at a speed between 1,400 and 1,600 meters per second, while in the atmosphere the speed of propagation is 340 meters per second.

Where does sound travel most easily?

Sound travels faster in hot air than in cold air. It is the deviation suffered by the waves in the direction of their propagation, when the sound passes from one medium to a different one.

Who is faster light or dark?

In physics there is an indisputable truth: no object can move faster than the speed of light; however, there is a premise that can cast doubt on this statement: darkness can be faster than light.

What is the speed of Mach 2?

It is a dimensionless number normally used to describe the speed of aircraft. Mach 1 equals the speed of sound, Mach 2 is twice the speed of sound, and so on.

What happens when the sound barrier is broken?

Breaking the sound barrier is a term used to explain what happens when a plane travels faster than the speed of sound, i.e. 343.2 meters per second (in the air). Exceeding that speed produces a shock wave that generates a huge noise.

What happens to an airplane when it exceeds the speed of sound?

In this situation, what is called a supersonic boom or shock wave occurs. It is as if the sound were accumulating by traveling at the same speed as the source that generates it.

What factors affect the speed of sound in air?

speed of sound in air

In this case the physical properties of the air, its pressure and humidity for example, are factors that affect the speed. For example, the higher the air temperature, the faster the propagation speed.

Why is the speed of sound higher in water than in air?

The speed of sound propagation in water is naturally higher than in air, because although water has a higher density () (and it takes more energy to move 1 cm3 of water than air) its modulus of (in)compressibility () is much higher, so the result of the propagation speed is…

How is the speed of sound broken?

Breaking the sound barrier is a term used to explain what happens when a plane travels faster than the speed of sound, i.e. 343.2 meters per second (in the air). Exceeding that speed produces a shock wave that generates a huge noise.

Who broke the sound barrier?

Chuck Yeager leaning against the X-1 with which he broke the sound barrier in 1947.

What happens if the speed of light is broken?

Exceeding that speed produces a shock wave that generates a huge noise, like an explosion that spreads through the air.
