No.
No, light does not always travel at the same speed in all mediums. Its speed can vary depending on the medium it is passing through.
They travel faster
no
They don't really travel at the same speed, but, on television, the distance they travel is so short, that the difference between the speed of sound and the speed of light is almost non-existant.
It was the same speed. It generally travel with 340ms-1 speed.
Waves of different wavelengths traveling at the same speed is a property of the medium through which they are moving. In a homogeneous medium, such as air or water, the speed of the wave is determined by the properties of that medium, like its density and elasticity. Therefore, waves with different wavelengths will travel at the same speed in that medium.
All photons travel at the same speed in a vacuum, which is the speed of light, but their velocities can vary when passing through different mediums.
All electromagnetic waves travel at the speed of light in a vacuum and can be characterized by their wavelength and frequency.
No, both light in air and radiation from a microwave oven travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second. Therefore, they both travel at the same speed.
speed?
All electromagnetic waves travel at the same speed in vacuum.
yes, comets travel around the solar system :l
