Question

A wave of infrared light has a speed of 6 m/s and a wavelength of 12 m. What is the frequency of this wave?

Answer 1

$\mathfrak{\huge{\green{\underline{\underline{Answer :}}}}}$

Speed = 6 m/s

Wavelength = 12 m

Frequency = 6/12 = 0.5 Hz

Answer 2

Answer:

The frequency of the wave is 0.5 hertz.

Explanation:

frequency=\frac{speed}{wavelength}

Given

speed=6\ m/s

and

wavelength=12\ m

we get:

frequency=\frac{6\ m/s}{12\ m}

\rightarrow frequency=0.5\ Hz
