Assertion (A): When lightning strikes, the light appears shortly after the sound is heard.
Reason (R): The velocity of light is greater than the velocity of sound.
Options:
(1) A is true but R is false.
(2) Both A and R are true and R is the correct explanation of A.
(3) A is false but R is true.
(4) Both A and R are true but R is not the correct explanation of A.

In reality, when lightning strikes, we see the light before hearing the thunder because the speed of light is much greater than the speed of sound.
Therefore, the Assertion is false, while the Reason is true.
