Yes, as long as it's traveling through the same material. If it enters a
different material, like water, glass, jello etc., then its speed changes.

What light travels the fastest red or yellow?

Light travels at the same speed regardless of its color. The speed of light in a vacuum is approximately 186,282 miles per second.


Is the speed of light greater or lesser in air than in water?

The speed is the same. Light travels at a finite speed.


Is the The speed of sound is the same the as speed of light yes or no?

No. Light travels much faster than sound.


What color travels the slowest?

All colors of light travel at the same speed in a vacuum, which is the speed of light. However, in mediums like air or water, the speed of light differs for different colors due to their different wavelengths and refractive indexes. Blue light generally travels slower than red light in these mediums.


Are speed of light and the frequency of light the same?

No, the speed of light is the speed at which a photon (the particles that make light) travels. While frequency is the number of times per a unit of time a wave cycles from peak to peak. Different frequencies produce different colours.


Which color of light travels fastest through a telescope lens?

All colors of light travel at the same speed in a vacuum, including through a telescope lens. The speed of light is determined by the medium it travels through; in air or a lens, all colors of light travel at the same speed.


Is red light slower than blue light?

No. Light travels at the same speed, regardless of color.


Is it true that sound travels at the same speed as light?

The speed of sound through air is about 340 meters per second. (The speed of sound in water is about 4 times faster than this). The speed of light in air is about 300 million meters per second.


Does light travels slowest through space?

Light travels fastest through space, as it does not encounter any obstacles to slow it down. In other mediums, such as air, water, or glass, light will travel at a slower speed due to interactions with the medium's particles.


What light travels the fastest in a vacuum ultraviolet or visible?

Light in a vacuum travels at the same speed regardless of its wavelength, known as the speed of light, which is approximately 299,792 kilometers per second. Both ultraviolet and visible light travel at this speed in a vacuum.


Is infrared light faster than microwave light?

Both infrared and microwave light travel at the speed of light in a vacuum, which is about 299,792 kilometers per second. Therefore, they both travel at the same speed.


How does the speed of a radio compare to the speed of visible light?

Radio waves and light are the same exact physical phenomenon, and differ only in their wavelength (frequency). Their speeds are identical.
