HOW MUCH SOUND OF THUNDER TRAVELS AND THE THUNDER'S SPEED CALUCLATE AND TELL MULTI PLICATION BY 189 INTO HOW MUCH SOUND OF THUNDER TRAVELS and THE THUNDER'S SPEED???\
Answers
Explanation:
Lightning and thunder are produced simultaneously, but the thunder is heard a few seconds after the lightning is seen. This is because the speed of light in air is more than the speed of sound in air.
The speed of light is given as 3×10
8
m/s. The speed of sound is 340 m/s. Thus, the entire time of 10 seconds (as mentioned in the question) between seeing the light and hearing the thunderstorm is taken by the sound to travel to the observer.

PHYSICS
The time interval between a lightning flash and the first sound of thunder was found to be 5 s. If the speed of sound in air is 330 ms
−1
, find the distance of flash from the observer.

ANSWER
The speed of the sound, distance traveled and the time taken relationship is given as follows.
Speedofsound=
Timetaken
Distancetravelled
From this equation the Distance traveled is derived as
Distancetravelled=Speedofsound×Timetaken
That is, Distancetravelled=330m/s×5seconds, given that the speed of sound is 330 m/s.
= 1650 meters.
