what is the wavelength of a wave with the speed of 680 m/s and the frequency of 400 hertz

Sagot :

Answer:

Wavelength of the wave is [tex]1.7[/tex] meter

Explanation:

As we know that

[tex]c = \lambda *v[/tex]

C is the speed of light

[tex]\lambda[/tex] is the wavelength of light

v is the frequency of the light

Substituting the given values in above equation, we get -

[tex]680 = \lambda * 400[/tex]

[tex]\lambda = \frac{680}{400}\\ \lambda = 1.7[/tex] m
