A stone thrown into still water, creates a circular wave pattern moving radially outwards. If

r

is the distance measured from the centre of the pattern, the amplitude of the wave varies as

View answer and explanation

Correct option: B

{r^{ - 1}}

Option B (

{r^{ - 1}}

) is correct because the amplitude of a circular wave decreases inversely with the distance from the center due to energy conservation.
