Arrange the following electromagnetic waves in increasing order of their frequencies (ie. begin with the lowest frequency):
Visible light, `gamma` rays, X-rays, micro waves, radio waves, infrared radiations and ultraviolet radiations.

Explanation

To arrange the given electromagnetic waves in increasing order of their frequencies, we need to understand the general frequency range of each type of wave. The electromagnetic spectrum is typically organized from the lowest frequency to the highest frequency as follows:

1. **Radio Waves**: These have the lowest frequency in the electromagnetic spectrum.
2. **Microwaves**: These have a higher frequency than radio waves.
3. **Infrared Radiations**: These come next, with frequencies higher than microwaves.
4. **Visible Light**: This is the range of frequencies that can be detected by the human eye.
5. **Ultraviolet Radiations**: These have higher frequencies than visible light.
6. **X-rays**: These have even higher frequencies than ultraviolet rays.
