What is the Speed if visible light in a vacuum?
it should be 3x10^8 m s^(-1). here is the calculation: we have known that the refractive index of vacuum is 1, by n= v/c ( n stands for refractive index of medium, v stands for the speed of light in medium, c stands for speed of light constant) 1=v/3X10^8 m s^(-1) v= therefore, speed of light in vacuum is 3x10^8 m s^(-1) actually, all light ray in electromagnetic spectrum have same speed in vacuum
Speed of red light and blue light in a vacuum?
In a vacuum the speed of red and blue light are the same as all light, 300,000,000m/s. Their frequency and wavelength will be different but the speed remains the same.
Is the speed of light changed when it is reflected back into the same medium?
No.
How does the speed of infrared radiation compare with the speed of x- rays when both speeds are measured in a vacuum?
If both speeds are measured in the same medium, whether it be vacuum, water, or jello, then they are equal.
Can the speed of light be changed?
no. speed of light is always constant . as long as the light stays in the same medium. the speed is generally slightly different in different media.
Does light always travel at the same speed?
The speed of light is always the same as long as it's traveling through the same medium. But its speed is different in different media, and those are all less than its speed in vacuum.
Is speed of light uniform or not?
The speed of light in a vacuum is constant everywhere. The speed of light in a particular medium depends on what the medium is. It moves slower in air than in a vacuum, and slower in water than in air.
What EM radiations travel the fastest from its source?
All electromagnetic radiation in a given medium (water, air, vacuum, etc) travels at the same speed, the speed of light in that medium.
Does light travels slowest through space?
As the medium through which light propagates in space is closes to a vacuum, light propagates very well in space. However, it travels at the same speed as it would on earth, as light travels at 299,792,458m/s in a vacuum, regardless of where that vacuum is located. the light travels in same speed whether it travels in space or earth.
What is the speed of light on the moon?
The speed of light in vacuum is the same everywhere.
Do radio waves travel through vacuum fasetr than visible light waves?
All electromagnetic radiation has the same speed in the same medium.
Does the color of a laser affect the velocity?
Light always travels at the same speed, the speed of light. At least in vacuum. In a medium light will travel at a slower pace, and the speed decrease is dependent on the color (wavelength) of the light. This is because the refractive index (which determines how fast light can travel through a medium) is color dependent.
What is the Speed if visible light in a vacuum?
it should be 3x10^8 m s^(-1). here is the calculation: we have known that the refractive index of vacuum is 1, by n= v/c ( n stands for refractive index of medium, v stands for the speed of light in medium, c stands for speed of light constant) 1=v/3X10^8 m s^(-1) v= therefore, speed of light in vacuum is 3x10^8 m s^(-1) actually, all light ray in electromagnetic spectrum have same speed in vacuum
Does light speed up or slow down when it leaves water into the air?
The speed of light in air is almost but not quite the same as its speed in vacuum,whereas its speed in water is about 25% less.So when light passes from air into water, its speed drops by about 25% .
Speed of red light and blue light in a vacuum?
In a vacuum the speed of red and blue light are the same as all light, 300,000,000m/s. Their frequency and wavelength will be different but the speed remains the same.
Why is the speed of the different colors of light in air the same?
All wavelengths are the same physical phenomenon ... electromagnetic radiation ... whose speed depends on the electrical properties of the medium in which it is propagating. Why would you think that they should travel at different speeds ?
What happens to frequency does the speed of light ever change?
The speed of light IN A VACUUM is always the same. In substances other than the vacuum, the speed of light is usually slower than in a vacuum.
