The rolling of thunder is caused by the successive reflections of sound waves from various reflecting surfaces, such as clouds and land, resulting in multiple echoes being heard.

Echoes may be heard more than once due to successive or multiple reflections of sound waves off various reflecting surfaces, such as clouds and land.
The sensation of sound persisting in our brain for about 0.1 seconds is crucial for hearing distinct echoes because it allows us to distinguish between the original sound and its reflected echo.
The speed of sound changes with the temperature of the air. As the speed of sound increases with higher temperatures, the minimum distance required for hearing distinct echoes also increases.
The minimum distance required for hearing distinct echoes is calculated by multiplying the speed of sound by the time interval (0.1 seconds) and halving the result. For example, at a speed of 344 m/s, the minimum distance is (344 m/s) ...
To perceive a distinct echo, the time interval between the original sound and its echo must be at least 0.1 seconds.
An echo is the reflection of sound waves off an obstacle, such as a tall building or a mountain, resulting in the same sound being heard again, albeit with a slight delay.
The reflection of sound follows similar principles to the reflection of light, obeying laws of angles and plane reflection. However, sound requires a solid or liquid medium to reflect off, while light can reflect off various surfaces, including gases and ...
The angle of incidence, which is the angle between the incoming sound wave and the normal to the surface, is equal to the angle of reflection, which is the angle between the reflected sound wave and the normal to the ...
An obstacle of large size, whether polished or rough, is needed for the reflection of sound waves. This surface acts as the reflecting medium for sound.
