Question

By increasing the wavelength, the frequency of the wave also increases.

• A. True
• B. False

Answer 1

The correct option is B False

An electromagnetic wave is characterized by its wavelength $\left(\lambda \right)$ and frequency $\left(\nu \right)$.
This is given by the equation:

$\nu =\frac{c}{\lambda }$, where $c$ is the speed of light.

They are inversely proportional to each other. Thus, by increasing the wavelength, the frequency of the wave decreases.
