Question

What is the wavelength of the wave above?

A- 0.75 cm
B- 1.5 cm
C- 2.5 cm
D- 3.5 cm

Answer 1

Answer ; 2.5 (C)

From the given figure it is cleat that the wave length (λ) = 2.5 cm

It is a "measure of distance between two identical crests or identical troughs in a wave.

In the figure, high points are crests and low points are troughs.
