Which electromagnetic waves have the highest frequencies in the electromagnetic spectrum?
2 answers:
<h2>Answer: Gamma Rays</h2>
Explanation:
The speed of an electromagnetic wave is given by:
(1)
Where is the frequency and
the wavelength.
Finding from (1):
(2)
As we can see, there is an inverse relation between the frequency and the wavelength (taking into account the speed of light is constant). This means, the smaller the wavelength, the greater the frequency.
Now, in the electromagnetic spectrum gamma rays has the smallest wavelength, in the order of . Therefore, gamma rays has the highest frequencies in the electromagnetic spectrum.

An element which is highly conductive, highly reactive, soft, and lustrous is most likely an alkali metal.
Alkali metals are in group 1 of the Periodic table which means that they have only a single valence electron.
This causes them to be soft and highly reactive because:
- The single valance electron leads to weak bonds amongst the element's atoms which makes them soft
- The elements want to lose the single valance electron so as to become stable so they will react with other elements to give away the electron.
Examples of alkali electrons include:
- Lithium
- Sodium
- Potassium etc
In conclusion therefore, alkali metals are highly reactive and soft and so the element described above is most likely an alkali metal.
