You create a vacuum in a lab, and then shine a light through it, and there is experimental proof that light travels through a vacuum. Alternatively, take the fact that light travels through space - if light could not travel through a vacuum, no light from the stars, the moon or the sun would ever reach our planet.
what is the material through which light travels
Light slows down when it travels through matter.The only time light travels at is maximum speed, c, is in a vacuum.
light travels from sun to earth through vaccum, so its easily understood
Light travels as light energy. Light is a type of electromagnetic wave.
glass
light is refracted when it travels through air and then through glass
Light travels fastest through vacuum.
light light
Light travels as light energy. Light is a type of electromagnetic wave.
by transmission , transmission is when the passing of light or other form of energy through matter .
Light travels fastest through space which has no air. Space is a vacuum which is the fastest way for light to travel.
