Video transcript

It is not possible to freeze a photon. Photons are elementary particles, the basic units of light, which always travel at the speed of light in a vacuum. They do not have mass and cannot be brought to a stop. However, research in quantum physics has shown that photons can be slowed down in certain media, but this is different from freezing or stopping them.

Questions and answers

  1. Why can't photons be frozen or stopped?

    Photons are massless particles that always travel at the speed of light in a vacuum, making it impossible to freeze or stop them.

  2. Can photons be slowed down?

    Yes, photons can be slowed down when passing through certain media, but this is different from freezing or stopping them completely.

  3. What does quantum physics say about the speed of photons?

    Quantum physics explains that while photons always travel at light speed in a vacuum, their speed can be reduced in some materials due to interactions.
