Question

Identify which one of the following can be represented by the product of the other two?
I. Speed
II. Wavelength
III. Frequency

• A. I
• B. II
• C. III
• D. Any one is the product of the other two
• E. None of the three is the product of the other two

Answer 1

The correct option is A I

Let the speed, wavelength and frequency of the wave to be represented by $v$, $\lambda$ and $\nu$ respectively.

$\therefore$ Speed $v=\lambda \times \nu$

Hence option A is correct.
