Question

Which electromagnetic waves have the highest frequencies in the electromagnetic spectrum?

Answer 1

xrays

Step-by-step explanation:

Answer 2

Answer: Gamma Rays

Step-by-step explanation:

The speed
`c` of an electromagnetic wave is given by:

`c=f.\lambda` (1)

Where
`f` is the frequency and
`\lambda` the wavelength.

Finding
`f` from (1):

`f=(c)/(\lambda)` (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
`10^(-6) nm`. Therefore, gamma rays has the highest frequencies in the electromagnetic spectrum.
