Given that

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

, where

\mathrm{y}

and

\mathrm{x}

are measured in metre. Which of the following statements is true?

View answer and explanation

Correct option: A

The unit of

\lambda

is same as that of

x

and

A

\lambda

is same as that of

x

and

A

) is correct because in the given equation,

\lambda

x

, and

A

all represent lengths and thus have the same unit.
