WBCS.LIVE practice question

Which of the following has the highest velocity?

Solve this multiple-choice question and check the correct answer with its explanation below.

Answer options

  1. Cosmic rays
  2. Light
  3. Electron
  4. Supersonic wave

Correct answer and explanation

Correct answer: Light

Explanation: āœ… Correct Answer: B) Light šŸ“š Explanation: Light travels at an absolute cosmic speed limit of approximately 300,000 kilometers per second ($3 \times 10^8 \text{ m/s}$) in a vacuum. This velocity is significantly higher than that of electrons or mechanical supersonic waves. According to the laws of physics, no material object or radiation can travel faster than the speed of light. Cosmic rays travel close to this speed, but light remains the absolute standard for maximum velocity.
