In this diagram a ray of light travels through air, Lucite, glass, and air again. Does light travel more quickly in Lucite or glass? Explain your responding.
Answers
Explanation:
the light travels more quickly through glass
Answer:
Light travels more quickly..
Explanation:
Light travels at approximately 300,000 kilometers per second in a vacuum, which has a refractive index of 1.0, but it slows down to 225,000 kilometers per second in water (refractive index = 1.3) and 200,000 kilometers per second in glass (refractive index of 1.5).
Speed of light is the lowest in diamonds.
Light has constant speed, only its frequency and wavelength varies
Speed of light does not change, it has to travel more in a medium than in vacuum,
When light is passing through a medium, the electrons in the medium absorbs the energy from the light and gets excited and releases them back. This absorption and re emission of light gives objects colour. Thus light interacts with the particle in the medium, which causes delay. But it’s speed remains same, only it has to travel more distance in the given time, so it seems that it’s speed is varying but it is not.
It is impossible for any physical object to travel at or more than speed of light.
The only reason why a photon can travel at light speeds is because it is mass less.
Any object having mass when tires to reach light speeds their mass increases, called relativistic mass.
So as it accelerates to reach light speeds it becomes more massive and a infinite energy is required to reach light speeds.
