GK Question

science medium true_false

True or False: The speed of light is maximum in glass compared to vacuum.

  1. True
  2. False

Answer: False

Light travels fastest in vacuum (≈3×10⁸ m/s). In denser media like glass, light slows down due to refraction, with speed reducing to about 2×10⁸ m/s. This principle is fundamental in optics. [[NCERT Physics Class 12]]
