Answer:
The frequency of the electromagnetic wave is 4.8 x 10¹⁴s⁻¹
In an Electromagnetic wave, The frequency , speed and wavelength of an are related by the formula
λ= c/f
where
λ = wavelength in metres, m.
c= speed of light in metres per sec, m/s
f= frequency in per seconds or hertz,( s⁻¹ , Hz)
Given that Wavelength of the electromagnetic wave is 6.25 x 10-7m.
We know that speed of light is 3 x 10⁸ m/s
Substituting the values into the equation becomes
f = c/ λ
f= 3 x 10 ⁸m /s / 6.25 x 10⁻⁷ m = 4.8 x 10¹⁴s⁻¹
Hence, The frequency of the electromagnetic wave is 4.8 x 10¹⁴s⁻¹
Explanation:
