If you were driving past a house as an explosion happened, how would it affect you?
1. It wouldn't alter what you heard at all: This answer is incorrect because an explosion produces a sudden burst of sound waves that would definitely be heard by someone driving past the house.
2. It would change the frequency because you were moving: This answer is correct. When you are moving in a car, the frequency of the sound waves that you hear can change due to the Doppler effect. As you drive towards or away from the source of the sound (in this case, the explosion), the frequency of the sound waves reaching you would be affected.
3. It would change the amount of light you see from the car: This answer is not relevant to the scenario of driving past a house during an explosion as light is not the main factor being altered in this situation.
4. It would change the amount of sound that bounces off trees: This answer is also not directly related to the scenario described. The main focus is on how the sound of the explosion would be perceived while driving past the house.
In conclusion, when driving past a house during an explosion, the frequency of the sound you hear would change due to the Doppler effect caused by your movement.
