Is it true blue light travels slower than red light because it has a shorter wave-length?

Nope, both travel at the same speed, the speed of light. the speed of light, c, is a constant and is approx. 3x10^8 meters per second
Blie light does indeed have a shorter wavelength than red light this results in it have a higher frequency.

No, the speed of light is constant in a vacuum and does not depend on the wavelength or color of light. However, when light travels through a medium like glass or water, different colors of light can be slowed at different rates due to the medium's refractive index, but this does not affect the speed of light in a vacuum.

Will a wavelength be shorter or longer the slower the object vibrates?
The wavelength will be longer if the object vibrates slower. Wavelength is inversely proportional to frequency; as frequency decreases, wavelength increases.
Why do wavelength of light changes when it travels from one medium to another?
When light travels from one medium to another, its speed changes due to the different refractive indices of the mediums. This causes the light to bend or refract, leading to a change in its wavelength while its frequency remains constant. This phenomenon is described by the principle of wavelength-dependent refraction known as Snell's Law.
Which travels faster in a vacuum - gamma rays or infrared rays?
Gamma rays travel faster in a vacuum compared to infrared rays. This is because gamma rays have a higher frequency and shorter wavelength, allowing them to travel at the speed of light. Infrared rays have a lower frequency and longer wavelength, which results in a slower speed when traveling through a vacuum.
Is light slower in air or water or a vacuum and Why?
Light travels fastest in a vacuum because there are no particles to interact with and slow it down. It travels slower in air and even slower in water due to the presence of molecules that can scatter and absorb light, causing it to travel at a reduced speed.
Light travels slower in a material with greater what?
Light travels slower in a material with greater optical density.
Will a wavelength be shorter or longer the slower the object vibrates?
The wavelength will be longer if the object vibrates slower. Wavelength is inversely proportional to frequency; as frequency decreases, wavelength increases.
Why do light waves have a far shorter wavelength than sound waves?
sound waves travel faster slower than light waves In air, sound travels around 300m/s.
Do you shake the end of the rope slowly or rapidly to make the wavelength shorter?
You should shake the end of the rope rapidly to make the wavelength shorter. Increasing the frequency of the wave by shaking it rapidly will decrease the distance between consecutive crests, thus shortening the wavelength.
Why does light travel faster in empty spaces?
Light travels faster (up to the speed of light) in a vacuum, which is empty space. Light travels slower through a medium (matter).
Why do wavelength of light changes when it travels from one medium to another?
When light travels from one medium to another, its speed changes due to the different refractive indices of the mediums. This causes the light to bend or refract, leading to a change in its wavelength while its frequency remains constant. This phenomenon is described by the principle of wavelength-dependent refraction known as Snell's Law.
What makes light move slower as it travels?
it moves slower because of sudden movement
Why is a plane seen before its heard?
because sound travels slower
Is Long wavelength visible light have a speed that is slower than short wavelength light which one?
In a vacum all wavelengths of light have the same speed of 3 x 10^8 m/s. However, in a medium like glass or water the speeds of light are different for different wavelengths and the longer wavelength has a higher speed then the shorter wavelength. Although both speeds are slower then their speeds in a vacum.
Which travels faster in a vacuum - gamma rays or infrared rays?
Gamma rays travel faster in a vacuum compared to infrared rays. This is because gamma rays have a higher frequency and shorter wavelength, allowing them to travel at the speed of light. Infrared rays have a lower frequency and longer wavelength, which results in a slower speed when traveling through a vacuum.

Light travels slower in a material with greater what?
Light travels slower in a material with greater optical density.
Which color of visible light travels the slowest through a glass prism?
Violet light tends to travel the slowest through a glass prism due to its shorter wavelength compared to other colors of visible light. This causes violet light to refract more as it enters and exits the glass, resulting in a slower speed.
