What is the wavelength of electromagnetic radiation with a frequency of 9.23 × 107 Hz?

Igoryamba

Answer:

The wavelength of the given electromagnetic radiation is 3.25 m.

Explanation:

We know that,

Frequency (f) = c / λ;

where,

c - speed of light = $3\times10^{8} m/s$

λ - wavelength of the radiation.

Given,

f = $9.23 \times10^{7} Hz$ ,

From the above formula,

λ = $\frac{c}{f}$

λ = $\frac{3\times10^{8} }{9.23\times10^{7} }$

λ = 3.25m;

Therefore,

Wavelength of the given radiation = 3.25 m

Which answer accurately describes the difference between speed and velocity?

irakobra [83]

I think the correct answer from the choices listed above is the second option. The difference between speed and velocity would be that speed <span> requires distance. Velocity requires displacement. Speed only has a magnitude while velocity is a vector quantity which means it has direction and magnitude.</span>
