A bomb explodes on the moon. How long will it take for the sound to reach the earth:
Correct answer: D. None of the above
- A. 10 sec
- B. 1000 sec
- C. 1 day
- D. None of the above
Explanation
When a bomb explodes on the moon- due to the vacuum there is no medium for the propagation of sound and hence it cannot reach the earth

About Speed of Sound
The speed of sound depends on the properties of the medium, including its elasticity and density, and in gases it varies mainly with temperature. Questions connect speed with frequency and wavelength, compare sound in solids, liquids and gases, and distinguish the speed of propagation from the oscillating particles' motion.

Laplace corrected Newton's formula for the velocity of sound in gas because the sound propagates:
The speed of sound in air at NTP is 300 ms-1. If the air pressure become 4 times; then the speed of the sound will be:
When the source is at the center of the circle and the observer is moving on the circumference of the circle, sound heard by the observer is:
If the speed of sound and wind are 345 m/s and 30 m/s respectively and is in opposite direction what sound speed is received by the listener:
The ratio between the velocity of sound in air at 4 atm and that at 3. atm pressure would be:
