Given that

y = A\sin \left[ {\left( {\frac{{2\pi }}{\lambda }\left( {ct - x} \right)} \right)} \right]

, where

y

and

x

are measured in metres. Which of the following statements is true

View answer and explanation

Correct option: A

The unit of

{\lambda ^{ - 1}}

is same as that of

\frac{{2\pi }}{\lambda }

Option A (The unit of

{\lambda ^{ - 1}}

is same as that of

\frac{{2\pi }}{\lambda }

) is correct because both terms represent inverse lengths and therefore have the same units.
