Question

Flash and Thunder are produced simultaneously for thunder is heard a few seconds after the flash is in my how does the speed of sound in air vary with rice in density of the medium

Answer 1

$\Huge{Answer with explanation}$

Flash and Thunder are produced simultaneously but thunder is heard a few seconds after the flash because $\textbf{ speed of sound in air is very less than speed of light in air. }$.

With the increase in the density of the medium , the speed of sound also increases.

For example, the density of Iron is greater than water. So, sound travels faster in iron than in water. That is why , it is difficult to hear sounds in water.

Answer 2

The speed of sound (344 m/s) is less than the speed of light (3 x 10^8 m/s).

Sound of thunder takes more time to reach the Earth as compared to light.

Hence, a flash is seen before we hear a thunder.
