The speed of sound through air is about 340 meters per second. It’s faster through water, and it’s even faster through steel. Light will travel through a vacuum at 300 million meters per second. So they’re totally different scales.

Using NASA’s Chandra X-ray Observatory, astronomers have seen that the famous giant black hole in Messier 87 is propelling particles at speeds greater than 99% of the speed of light.

The speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour. Visible light can also travel through other things besides through air and through space.

Yes, wind can travel faster than the speed of sound. Wind is just the bulk movement of a mass of air through space and is in principle no different from a train speeding along or a comet zipping through space. The speed of sound just describes how fast a mechanical wave travels through a material.

Light travels faster than sound even in water. If you are asking why sound is slower when it is in air than water, and why light is faster in air than in water, here is why: Light waves are electromagnetic transversal waves. They can travel through a vacuum and any particles they contact slow them down.

“Nothing can travel faster than the speed of light in a vacuum.” “Light in a vacuum always travels at the same speed.” Those additional three words in a vacuum are very important. Light traveling through anything other than a perfect vacuum will scatter off off whatever particles exist, as illustrated below.

Violet colour

violet light

So violet color has minimum velocity of light and red color has maximum velocity of light when it passes through the glass. Hence the red color of white light travels fastest in the glass.

White light is a combination of all colors in the color spectrum. It has all the colors of the rainbow. Combining primary colors of light like red, blue, and green creates secondary colors: yellow, cyan, and magenta.

Solution. Red colour travels fastest and Blue colour travels slowest in glass.

Yes light travels faster in vacuum than any other medium. This is because there is no obstruction in vacuum for the propagation of light and thus, the refractive index of vacuum is the lowest. Show the speed of light in vacuum is the maximum.

299,792, 458 m/s.

This is because different colors of light travel at *different speeds* in the glass. Blue light travels slightly slower in glass than red light, so it bends a sharper angle when it enters the glass from air. In physics, we say the glass has a higher refractive index for blue light than red light.

When travelling through a medium the frequency remains unchanged and hence, speed depends upon the wavelength of light. Violet light having the least wavelength travels slowest.

Speed of Light Light travels at almost 300,000,000 meters per second (to be exact: 299,792,458 meters per second) in a vacuum.

The bending occurs because light travels more slowly in a denser medium. The amount of refraction increases as the wavelength of light decreases. Shorter wavelengths of light (violet and blue) are slowed more and consequently experience more bending than do the longer wavelengths (orange and red).
