    Answer: False

    Light can travel through various materials like air, glass, water, oil, diamond etc. The speed of light is greatest in air and reduces as the material is dense. The light travels slowest in diamond. So, light travels with different speeds in different materials. In one material it travels with same speed always. The speed changes after zone boundary of any material.
