Science fiction movies sometimes take place in space and contain scenes where things explode very loudly and brightly. Why is this unrealistic? (1 point)
•The pressure in space would keep explosions from being very large.
© Light waves cannot travel through the vacuum of space.
O Large explosions are more likely to create seismic waves, not sound and light.
• Matter is needed to transmit sound waves.
The correct answer is: © Light waves cannot travel through the vacuum of space.
In space, there is no air or medium for sound to travel through. Sound waves require a medium, such as air or water, to propagate. Therefore, explosions in space would be silent. Similarly, light waves can travel through space, but they would not create the bright and colorful explosions typically depicted in science fiction movies. These explosions would only be visible if there were particles or gases present to reflect or scatter light.
The correct answer is:
- Matter is needed to transmit sound waves.
In space, there is a vacuum, meaning there is no air or medium to transmit sound waves. Since sound requires particles to vibrate and carry the sound waves, explosions in space would not produce any sound. Therefore, scenes in science fiction movies where explosions are accompanied by loud sounds are unrealistic.
The correct answer is: The pressure in space would keep explosions from being very large.
In space, there is no air or any other medium to transmit sound waves like there is on Earth. Sound waves require a medium, such as air or water, to travel through. In the vacuum of space, there is no medium for sound waves to propagate, so we wouldn't hear the explosion. The absence of air also means that there is no medium for the resulting shockwave to travel through, which would limit the size and impact of an explosion in space. Therefore, the loud and booming explosions depicted in science fiction movies set in space are unrealistic.
