प्रश्न
Answer briefly.
Why light waves travel in a vacuum whereas sound waves cannot?
Advertisements
उत्तर
Light waves are electromagnetic waves that can travel in a vacuum where sound waves travel due to the vibration of particles of the medium. Without any particles present (like in a vacuum) no vibrations can be produced. Hence, the sound wave cannot travel through the vacuum.
