What is the wavelength of a wave that has a frequency of 6.1⁢ x⁢ 109⁢ ⁢Hz ? c⁢ = λυ where c = 2.998 x 108⁢ m/s
a. 20.4 m
b. 2.04 m
c. 0.49 m
d. 0.049 m

Sagot :

Answer:

Wavelength = 0.049 m

Explanation:

Given that,

The frequency of a wave,[tex]f=6.1\times 10^9\ Hz[/tex]

We need to find the wavelength of the wave. We know that,

[tex]c=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{2.998 \times 10^8}{6.1\times 10^9}\\\\\lambda=0.049\ m[/tex]

So, the wavelength of the wave is 0.049 m.
