In a movie, while showing the explosion of a spacecraft in space, a flash of light is shown along with sound at the same time. What are the errors in this depiction?

  • 1

The major errors are hearing sound in outer space, which is a vacuum where mechanical waves cannot travel and depicting sound and light reaching the observer simultaneously despite vast speed differences.

    1. (i) Sound propagation error: Outer space is a near vacuum lacking a material medium and since sound is a mechanical wave requiring matter to propagate, no explosion sound can travel or be heard. (ii) Simultaneous arrival error: Even if gas were present, light travels at nearly 300,000 km per second, meaning visual flash would always arrive long before any acoustic disturbance.
